Sushobhna Batra

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.

I earned my bachelor’s degree in cell biology at the University of Mary Hardin-Baylor, and worked as a research technician in physiology and regenerative medicine at Texas A&M. in 2019 I joined the Diamond lab, where I specialize in cell culture and molecular biology techniques. I enjoy reading, chess, and being a brony.


Vaibhav Bomareddy

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.

Research Associate (Lab Manager)
I received my bachelor of science in 1999 from Randolph-Macon Woman’s College in Lynchburg, Virginia. 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 recently 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.

I enjoy being with my family, reading and spending time in nature.


Haris Girish

Haris Girish, D.V.M., Ph.D.

Research Scientist
I am from Chennai, India, where I earned my doctorate in veterinary medicine at Madras Veterinary College. After working as a veterinarian, I earned my master’s and doctoral degrees in animal genetics at MVC. As a postdoctoral associate at Baylor College of Medicine in Houston, I studied the effects of gut microbiome on lactation in mice. I recently joined the Diamond lab, and currently support the ongoing research.


Ankit Gupta

Ankit Gupta, Ph.D.

Postdoctoral Researcher
Raised in Rajasthan, India, I earned my master's degree in microbiology from Nirma University, Ahmedabad, and my Ph.D. from the Indian Institute of Science Education and Research, Bhopal. In the Diamond lab, my research interest is generating novel reagents — nanobodies, single-chain antibodies, and antibodies — that can distinguish pathogenic and non-pathogenic conformations of tau protein and can bind to pathogenic strains of tau. I am also developing early diagnostic tools to characterize various pathogenic protein aggregates.


Krishanna Knight

Lab Technical Assistant II
A Dallas native, I am working on my associate’s degree in veterinary technology at Cedar Valley College. I joined UT Southwestern as an animal tech, and in August 2019 joined the Diamond/ Bailey labs. I will soon complete my certification as an laboratory animal technician. Outside of work, I enjoy spending time with my husband and daughter, having family get-togethers, traveling, and having fun!

A native of Toronto, I earned my bachelor’s in pharmacology from McGill University. I am pursuing my doctorate at McGill, using PET imaging to characterize tau aggregation. In the Diamond lab, I employ biochemical techniques to determine how PET radiopharmaceuticals bind to tau. When asked how I spend my free time, I laugh at the notion of “free time.”

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.
