Graduate Student: Immunology
Raised in Delhi, India, I came to the U.S. for my studies, graduating from SUNY Buffalo with a B.S. in biochemistry and biology and a minor in pharmacology and toxicology. As the only immunology student in the Diamond lab, I focus on the role of the immune system in tauopathies, studying cellular tau entry and transfer of tau aggregates between astroglia cells, as well as identifying the proteins that play a part in the aggregation and release of tau. I enjoy sketching, stand-up comedy, and nephology.

Vaibhav Bomareddy

Research Technician I
I was born and raised in Houston, TX, and received my bachelor's degree in neuroscience from UT Dallas. I started in the Diamond lab as an undergraduate through the Green Fellows program, and am continuing as a research technician before beginning medical school. I am working with Jaime Vaquer-Alicea to develop an alanine scan that can discriminate between tau aggregates, to relate tau conformers with overall disease pathology.

Julita Chlebowicz

Julita Chlebowicz, M.S.

Graduate Student: Cell and Molecular Biology
I earned my master's in biotechnology from the Warsaw University of Technology. I came to UTSW to study WNK kinases under Dr. Elizabeth Goldsmith in the Biophysics Department. The diverse opportunities here inspired me to apply to the graduate school. Currently, I am developing biosensors to detect protein aggregation of alpha synuclein, amyloid beta, and tau. When I’m not racking my brain trying to understand these proteins, I can be found painting, at the theater, or exploring the United States.

My career began at the University of Virginia in Charlottesville, followed by the University of Louisville in Kentucky, and Washington University in St. Louis, Missouri. I recentenly earned certification as an assistant laboratory animal technician (ALAT). I am an avid local tourist and I dote on my fur-baby, Dolche, a Chihuahua/terrier mix.

Dana Dodd, Ph.D.

Senior Research Scientist
I received my B.A. in biochemistry and molecular biology at UC Santa Cruz and my Ph.D. in microbiology and immunology from Stanford, where I studied poliovirus proteins. For my postdoc, I worked at the University of Zurich, investigating the neurite inhibitor Nogo-A. I then moved to UTSW’s Microbiology Department, where I discovered how a bacterial protein inhibits phagocytosis. Now, in the Diamond lab, I employ CRISPR-Cas9 screens to find proteins involved in tau seeding and propagation.

Michael LaCroix

Michael LaCroix

Graduate Student
I grew up in Buffalo, Minnesota, and earned a B.S. in neuroscience with a minor in psychology at the U of M Twin Cities. I am pursuing a joint M.D./Ph.D. through UTSW’s Medical Scientist Training Program. I investigate the diversity of diseases that may contain tau prions, especially inflammatory brain conditions. We hope to uncover the breadth of tau pathology, and better understand factors that initiate tau seed formation. I enjoy rock climbing, playing music, spending time with my family and friends, and petting my two cats.

Ayde Oliva, M.S., Ph.D.

Postdoctoral Fellow
I grew up in Hidalgo, Mexico, and earned my B.S. degree in biomedical research, and my M.S. and Ph.D. in biochemistry, at the National Autonomous University of Mexico. In the Diamond lab, I study the relationship between the conformational diversity of tau protein aggregates and other amyloid proteins present in neurodegenerative diseases. We think that co-existence of a specific tau strain with certain states of associated proteins could define the neuropathology and clinical symptoms of neurodegenerative disease.
