Doctor of Philosophy

Charlie Bond
Mentor: Melike Lakadamyali, PhD
Microbiology, Virology, and Parasitology Program
Thesis Title: Multiplexed DNA-PAINT Imaging of the Heterogeneity of Late Endosome/Lysosome Protein Composition
Mentor Comment: Charlie’s thesis worked used cutting-edge multiplexed and quantitative super-resolution microscopy methods to visualize multiple lysosomal proteins simultaneously at single organelle resolution. He revealed, for the first time, that lysosomes exist in distinct molecular subpopulations, each containing a unique combination of lysosomal proteins. These findings have opened an entirely new avenue of research in my lab and multiple national and international research groups have reached out to collaborate to extend these findings, underscoring the impact of Charlie’s work. In addition to his own science, Charlie has worked collaboratively to disseminate the cutting edge imaging technologies both within the lab and to collaborators and he is a well-deserved co-author on several papers. Beyond his exceptional research accomplishments, Charlie has been a transformative force in our department’s culture, spearheading multiple initiatives, including the creation of DOPAMINE (Department of Physiology Alliance for Mentorship, Interconnectedness, Networking, and Enrichment), which has played a crucial role in fostering a sense of belonging for trainees and staff. Charlie is the full package—an intellectual powerhouse, a master of cutting-edge technologies, a great team player and a dedicated advocate for a better scientific community. He has left a lasting mark on my lab and he will be missed.

Thesis Title: Virulence properties of the pediatric pathogen Kingella kingae
Mentor Comment: Kevin has developed into an outstanding scientist. His thesis work provided major advances in our understanding of virulence determinants in Kingella kingae, an emerging pediatric pathogen. In particular, he discovered a novel K. kingae outer membrane lipoprotein that binds human factor H and mediates high-level resistance to complement-mediated serum killing, promoting bacterial intravascular survival and facilitating dissemination to bones and joints. In addition, he established that the K. kingae type a and type b polysaccharide capsules have unique pathogenic properties, accounting for the observation that strains producing the type a or type b capsule account for over 95% of invasive K. kingae disease. Beyond his own work, he consistently offered important perspectives on the work of other members of the lab.

Beatrice Herrmann
Mentors: Igor Brodsky, PhD
Microbiology, Virology, and Parasitology Program

Thesis Title: Durable cardioprotection by AAV9-μUtro gene therapy for Duchenne muscular dystrophy
Research and Lab Description: My thesis work demonstrated that our gene therapy for Duchenne muscular dystrophy was protective in the murine against cardiac injury and maladaptive cardiac remodeling, and protection was durable out to 10-months post-treatment or the human equivalent of age 40. My PhD lab was the lab of elite athletes. My PI had trained at the Olympic training center for cross country skiing and still competes at Master's World Championships, my labmate runs marathons, and I competed for the U.S. Team in rowing 3 times during my PhD. Grateful for an environment that supported both scientific and athletic passions.
Post PhD Plans: I am currently working as a post-doc in my PhD lab but disclaimer -- we are on track with the NIH and FDA to a clinical trial for our gene therapy for kids with Duchenne muscular dystrophy. I am honored to be in a position to see 30 years of work in this field finally translate from bench to bedside.

Victoria Lovins
Mentor: Elizabeth Grice, PhD
Microbiology, Virology, and Parasitology Program
Thesis Title: Impact of Staphylococcus aureus Strain-Level Variation on Cutaneous Leishmaniasis
Mentor Comment: It was a distinct pleasure and honor to be Victoria (Tori) Lovins’ PhD mentor. Tori showed incredible perseverance, determination, and commitment during the course of her studies, despite multiple severe disruptions that threatened to derail her work, including a pandemic and a lab fire. Tori produced a body of work that was technically challenging and required her to pioneer several new models and techniques to analyze host-microbiota-parasite interactions. As our lab’s resident expert in interpreting flow/immunology data, she selflessly contributed to a wide range of projects. Her dissertation, which was also supervised by Dr. Phil Scott, bridged basic science with translational studies to understand the mechanisms whereby the colonizing microbiota mediates the severity of cutaneous leishmaniasis infections. In addition to being a stellar scientist, Tori is also one of the kindest, most empathetic and aware people I have had the opportunity to train. We in the Grice and Scott labs are so proud and wish her all the best as she pursues post-doctoral training in Sweden!

Daniel Morris
Mentor: George Shaw, MD, PhD
Microbiology, Virology, and Parasitology Program
Thesis Title: Transient glycan-shield reduction induces broadly neutralizing HIV-1 antibodies in SHIV-infected rhesus macaques
Research and Lab Description: The Shaw lab is interested in deciphering the virus-antibody co-evolution that occurs in a rhesus macaque model of HIV infection to inform vaccine design. During my PhD, I designed two novel infection models to increase the frequency that infected macaques develop broadly neutralizing HIV antibodies.
Post PhD Plans: I'm staying on in the Shaw lab as a post-doc to wrap up some additional projects while I transition to a role in vaccine development at a pharmaceutical/biotech company.
Mentor Comment: Danny was an exceptional graduate student who tackled an extremely challenging problem: How can broadly neutralizing antibodies targeting the CD4 binding site (CD4bs) and fusion peptide (FP) of HIV-1 be elicited at high frequencies in a nonhuman primate model? In a series of published manuscripts, Danny showed that by deleting glycan residues adjacent to the CD4bs and FP epitopes in novel simian-human immunodeficiency viruses (SHIVs), he could immunofocus naïve germline B cells to target these epitopes and then affinity-mature them to acquire neutralization breadth and potency. Finally, he showed that such bNAbs were effective in preventing productive clinical infection by heterologous SHIVs in a rhesus macaque challenge model.

Kara Nelson
Mentor: Stephen DiNardo, PhD
Developmental, Stem Cell, and Regenerative Biology Program
Thesis Title: The Drosophila hematopoietic niche assembles through collective cell migration controlled by Slit-Robo signaling
Mentor Comment: Careful as a scientist, and wicked sharp. Kara’s goal is to ‘do something that matters’. I am confident that she will. I am also grateful she selected our lab as a way station to simply do something no one had done before (rather than something that helped others), while she figures out her next step.

In addition, she was a central pillar of the lab as we navigated the Covid pandemic and other major challenges. I am looking forward to seeing what she does next.

Stefan Peterson
Mentor: Igor Brodsky, PhD
Microbiology, Virology, and Parasitology Program
Thesis Title: Bacterial population dynamics and host factors influencing Yersinia extraintestinal dissemination
Mentor Comment: Stefan was an outstanding PhD student! Stefan joined the Brodsky lab in spring 2020 in the midst of the pandemic. In fact, Stefan was rotating in the lab when we shut down. Stefan navigated the lab research shutdown and associated challenge of developing a project while having to social-distance with poise and good humor. Stefan worked on at least three different projects before landing on what became his final magnum opus – developing a barcoding system to track bacterial infection in vivo. This was a tour-de-force of effort and insight and led to multiple co-authorships on papers from the lab along with revealing new insights into how bacteria spread from the intestinal tissues to systemic sites during bacterial infection. Beyond his work in the lab, Stefan also served as student representative for BGSA, as finance chair of LTBGS, and as a member of the executive board of the Science Policy and Diplomacy Group. I was lucky to have had Stefan as a PhD student in my lab. Congratulations Stefan!

Mentor: Igor Brodsky, PhD
Microbiology, Virology, and Parasitology Program
Thesis Title: Sequentially activated death complexes regulate pyroptosis in response to Yersinia infection
Research and Lab Description: I really enjoyed my time in the Brodsky lab. Science wise, the lab provided me with extensive training in microbiology and innate immunity. During my thesis, I studied how the bacterial pathogen Yersinia induces cell death in host immune cells. My thesis identified a novel role for how caspases, the executioner proteases of cell death, communicate with one another, and the molecular complexes that form within our cells when they undergo bacterial-induced cell death. Socially, I felt privileged to work with my PI Igor Brodsky and the rest of my labmates- I learned so much from them and value them as scientists and close friends!
Post PhD Plans: I am currently a postdoctoral fellow at NIAID studying lung inflammation and fungal infections- ultimately, I want to pursue a career in industry/biotech!
Mentor Comment: It was wonderful having Ronit as a PhD thesis student in the lab. Ronit joined my lab in spring 2020 in the midst of the pandemic. Ronit navigated the lab research shutdown and associated challenging of developing a project while having to social-distance with grace and patience. Ronit worked on a longstanding project in the lab that had to do with understanding how cells undergo cell death with ostensibly simultaneous activation of multiple markers of different death pathways. Ronit also contributed to a project on understanding intracellular sensing of bacterial lipopolysaccharides. In addition to her amazing science, Ronit was the lab social coordinator (mostly related to getting the lab to Phillies games). Ronit co-authored multiple manuscripts and mentored multiple students in the lab. I am grateful to have the opportunity to mentor Ronit for her PhD thesis work. Congratulations Ronit!

Thesis Title: Uncovering the Role of CD38 in T cells
Mentor Comment: Kim’s thesis research illuminated the role of the activation marker CD38 in T cells. Kim showed that CD38 provides a subtle inhibitory effect on activated T cells and that CRISPR-mediated deletion of CD38 enhances the anti-tumor function of CAR T cells. In addition to her academic achievement, Kim was a model lab citizen and a friendly and pleasant collaborator.

Gabriela Vida
Mentor: Stephen DiNardo, PhD
Genetics and Epigenetics Program
Thesis Title: Niche cytoskeletal architecture is required for proper stem cell signaling and oriented division in the Drosophila testis
Research and Lab Description: My thesis investigates how niche structure is required for the proper behavior of stem cells in the Drosophila testis. I was fortunate to do this work under Steve DiNardo’s mentorship, who I wouldn’t have been able to do this without.
Post PhD Plans: I am now a Post-doctoral fellow in Priya Sivaramakrishnan’s lab at CHOP where I’m investigating transcription elongation rates effects on the developing C. elegans embryo.
Mentor Comment: Agreeing to disagree on fútbol, but agreeing on everything else that mattered. Gabby’s industriousness and stick-to-it-ness will serve her and her future science efforts well, as they did in our lab. And, as a virtual side project (pun) she spearheaded a multilab effort to spread good vibes about little fly testes scRNAseq, making the richness of that data set clear to all.

Bailey Warder
Mentor: Stephen DiNardo, PhD
Genetics and Epigenetics Program
Thesis Title: An actomyosin network organizes niche morphology and responds to feedback from stem cells
Research and Lab Description: My thesis work focused on unveiling the mechanisms that shape a functional stem cell niche. I uncovered an exciting feedback loop in which stem cells help shape the niche that guides their behavior. The DiNardo lab was the most supportive environment for my growth as a scientist, and I would not be here today without Steve's constant encouragement, humor, positive attitude, and silliness.
Post PhD plans: I am incredibly lucky to be working as a Postdoc in the lab of Dr. Eric Joyce at Penn. I already have learned so much by surrounding myself with the intelligent and thoughtful lab that Eric has cultivated. Here, I am studying the role of 3-dimensional genome organization on cellular function and organism development.
Mentor Comment: A confident scientist (yes, you are). Bailey took command over her research and became an exemplary model for how to communicate that science. And, did I mention that the work was significant, too?

Brandon Wenz
Mentors: Casey Brown, PhD; Ben Voight, PhD
Genetics and Epigenetics Program
Thesis Title: Mapping Chromatin Accessibility in Humans to Decode the Genetic Mechanisms Underlying Complex Traits
Mentor Comment: I feel incredibly fortunate that Brandon found his way to my lab after the untimely passing of his graduate advisor, Casey Brown, who is sorely missed. While I'm certain that my group provided a needed waystation to complete his work, I don't think Brandon appreciated how much his presence in the lab - a dedicated soul committed to working hard, thinking critically, and supporting other lab members - was so extremely valuable to my own group over these past years. I am so impressed by his development with capabilities in both the wet and dry-lab (computational) experimental spaces. Talking science and ideas with him has been a real treat and I will very much miss these exchanges with him. Brandon -- mate -- I'm super proud and excited for you as you are able to take the next steps in your scientific career!

My thesis unveiled the role of pulmonary venous endothelial cells in lung regeneration under the guidance of Dr. Andy Vaughan, who has been an exceptional and supportive mentor.
Mentor Comment: Joanna absolutely killed it in the Vaughan lab!! You’d be hard pressed to find a more intelligent, hard working, kind, funny, and all-around awesome grad student. I owe her tremendously for the contributions she made in making my lab what it is today, and I have no doubt there are big exciting things in her future!!
Combined Degree, MD-PhD

Erin Hollander
Mentor: Ben Stanger, MD, PhD
Cancer Biology Program
Thesis Title: Sugar power: N-glycosylation and its role in anti-tumor immunity
Mentor Comment: I feel quite fortunate to have had Erin as a thesis student. Her project – examining how altering glycosylation patterns in tumor cells influences anti-tumor immunity – involved a windy path of discovery. Erin followed the data where it led, without fear or favor, ultimately identifying a novel phenomenon whereby glycosylation alters tumor cell death thresholds. This was a new area for the lab, and so Erin had to master the field and then teach us all. Now that she has returned to medical school, I know her patients will benefit from her presence as much as we have!

Mentor: Arjun Raj, PhD
Genetics and Epigenetics Program
Thesis Title: TRANSCRIPTION FACTOR AP-1 MEDIATES CELLULAR ADAPTATION AND MEMORY FORMATION IN MELANOMA THERAPY RESISTANCE
Mentor Comment: Jess is an incredible scientist and person. Her work stands to upend a lot of how we think about the limitations of gene regulation by showing that cells are able to "learn" by dynamically rewiring their regulation in a sequence-independent manner. She is a model lab member, always ready to lend her insights or a pair of hands to help her fellow lab mates.

Thesis Title: Glutamine availability regulates tissue-specific cDC subsets
Mentor Comment: Graham is a very talented young scientist who combines creativity, imagination, and perseverance to produce high quality work that has significant clinical implications. During his Ph.D., he uncovered the relationship of glutamine availability to anti-tumor immune responses. Given this pathway is now being targeted in clinical trials to treat pancreatic and other cancers, his findings will be critical to how glutamine antagonists could be deployed in future cancer treatments.

Mentor Comment: Claudia is an incredible scientist! She tackled a challenging project and unraveled the mechanism to explain how Xist deletion in B cells alters B cell fate and function, resulting in autoimmune disease phenotypes in mice. She is a natural leader, and will become an incredible physician scientist!

Emily Lubin
Mentor: Elizabeth Bhoj, MD, PhD
Genetics and Epigenetics Program
Thesis Title: Germline Histonopathies and Beyond: Integrating patient-directed insights with large-scale data to understand rare Mendelian neurodevelopmental disorders
Research and Lab Description: My research focused on gaining insights into emerging ultra-rare neurodevelopmental disorders caused primarily by germline variants in histone-encoding genes through genotype-phenotype analyses, utilization of AI/ML based next-generation phenotyping, interrogation of publicly-available databases, international collaborations, and most importantly partnerships with patient families.
Post PhD Plans: I have returned to medical school to complete my MD/PhD training and plan to apply to Pediatrics Residency programs this fall!
Mentor Comment: Emily created an elegant thesis bridging clinical and research human genetics. Her work brought together hundreds of patients with germline histone mutations to discover similarities between different syndromes to move forward diagnosis, mechanistic understanding, and targeted treatments more quickly than just individuals.

Thesis Title: Mitochondrial function regulates SARS-CoV-2 replication and pathogenesis
Research and Lab Description: My dissertation research uncovered aspects of mitochondrial function that serve to limit SARS-CoV-2 replication and established a causative relationship between subtle mitochondrial variation in the host and differences in murine SARS-CoV-2 pathogenesis, paving the way for metabolically informed antivirals and biomarkers for COVID-19. Despite founding the field of mitochondrial genetics, Dr. Wallace always made time for me: from brainstorming exciting ideas, to developing stories for publications, grant applications, or talks, or helping me cope with my dad developing ALS and dying during my PhD. I truly believe our projects would have been half as successful without his guidance as well as the collaborations and nurturing lab environment he creates.
Post PhD Plans: My supportive thesis mentor, lab, as well as other CHOP and Penn faculty mentors connected me with incredible scientists and physician scientists around the world as I pivot into a very personal endeavor: I’ve decided to switch research fields and leverage my MD-PhD training to eliminate C9orf72 ALS/FTD from my family tree.
Mentor Comment: Ms. Soto Albrecht is an exceptional talent. She joined our team with a background in virology and combined that expertise with mastering the intricacies of mitochondrial biochemistry and genetics. Working with SARS-CoV-2 required studies under BSL-3 level containment. Mrs. Soto Albrecht traveled repeatedly to the National Emerging Infectious Disease Laboratory (NEIDL) in Boston to become certified to work at the BSL-3 level. She then performed rigorous SARS-CoV-2 studies at NIEDL, in the University of Pennsylvania BSL-3 laboratory, and at the Center for Mitochondrial and Molecular Medicine (CMEM) in the Children’s Hospital of Philadelphia (CHOP). Her results demonstrated that SARS-CoV-2 inhibition of mitochondrial function is central to viral pathogenicity. Dr. Soto Albrecht has returned to the clinics to complete her MSTP medical training.
