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.
Research Technician II
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.
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.

Behavioral Neurology Fellow
I started at the Center for Alzheimer's and Neurodegenerative Diseases in 2017 during my Neurology residency. My research focuses on harnessing the insights and tools developed by the Diamond lab’s basic research to directly benefit patients with neurodegenerative diseases. By targeting the molecular changes that underlie these diseases, we hope to develop new methods for diagnosis and treatment.

I am from India, and earned my Ph.D. at the National Centre for Biological Sciences in Bangalore, where I studied lipid signaling in neuronal cells. I joined the laboratory in August 2017. I am interested in understanding the mechanisms and machinery that underlie the progressive spread of tau. I am currently working on a screen, using advanced genetic methods, to identify the molecules involved in the spread of tau.
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.
Anuja Modi, M.S., Ph.D.
Senior Research Associate
I am from Mumbai, India, where I received my B.S. in pharmaceutical sciences. In the U.S., I earned an M.S. in medicinal chemistry and Ph.D. in biochemistry. For my postdoc, I moved to UTSW to work on identifying small-molecule inhibitors of kinases as cancer therapy. Now in the Diamond lab, I use my skills in assay development and high throughput screening to identify small-molecule inhibitors of tau that could eventually be used as drugs to block misfolded tau or as diagnostic agents. Outside of research, I enjoy reading and traveling.
Ayde Oliva, M.S., Ph.D.
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.
Graduate Student: Molecular Biophysics
I was born and raised in Laredo, Texas, and received my B.S. in chemical engineering from Stanford University. Now, under the guidance of my co-mentors, Drs. Lukasz Joachimiak and Marc Diamond, I investigate the roles that different molecular chaperones play in neurodegenerative diseases. I am also interested in developing novel therapeutic and imaging strategies for neurodegenerative diseases. I enjoy collecting cute things, making origami sculptures, and trying to keep my plants alive.

I received my bachelor's degree in biochemistry from Cornell, and my Ph.D. in molecular biophysics and biochemistry at Yale. I came to UTSW as a postdoc, and then became a research-track professor in the Green Center for Systems Biology. I study the types of energetic interactions that establish protein structure and function, how they are distributed in proteins, and how evolution guided the organization of natural proteins. I am now identifying the sequence determinants underlying high-order protein aggregatation.
Clarissa Valdez, Ph.D.
I am from Chicago, and received my B.A. in molecular biology from Pomona College. I then earned my Ph.D. in neuroscience from Northwestern University.
