Sarat Vatsavayai received an MSc degree in Human Genetics from Andhra University, India. He then did his doctoral work in the field of Huntington’s disease at the Open University, UK, where he was charactering a novel mouse model and was trying to find out if DNA repeat instability could modify disease progression. In July 2013, he joined Dr. Seeley’s lab and is studying the molecular basis of C9ORF72 mutation in frontotemporal dementia and amyotrophic lateral sclerosis.

Salvatore Spina, MD - Assistant Professor 

Dr. Spina received his medical degree from the University of Catania, Italy. He completed a neurology residency at the University of Siena, Italy from which he also obtained his doctorate degree on mechanisms of neurodegeneration. He was trained in neuropathology of dementia syndromes at the Indiana Alzheimer Disease Center, Indianapolis in the laboratory of Dr. Bernardino Ghetti. Later, he completed an internship in internal medicine and a neurology residency at Indiana University. Dr. Spina’s research focuses on the clinicopathologic and genetic correlations in neurodegenerative dementia syndromes, with a special interest on frontotemporal lobar degeneration. He has been awarded the Best Young Investigator Award from the European Confederation of Neuropathological Societies (Euro-CNS) and the Hellenic Society of Neuropathology.

Norbert Lee - Staff Research Associate

Norbert Lee joined the lab as a Staff Research Associate in 2010. He assists with brain banking and other histology technician responsibilities.


Sarah Kaufman, MD, PhD - Memory and Aging Center Research Fellow

Sarah Kaufman received her undergraduate degree in Molecular and Cell Biology, with a focus in Neuroscience from the University of California, Berkeley. She completed her MD/PhD through Washington University in St. Louis MSTP. Her graduate research focused on tau aggregation and tau strain biology in the laboratory of Marc Diamond. After completing her dual degree she began Neurology residency at the University of California, San Francisco. After graduation from residency, she will begin a research fellowship through the Memory and Aging Center, with joint mentorship in the Seeley and Kampmann laboratories. Her ongoing research interests include understanding the mechanisms that underlie selective vulnerability in frontotemporal dementia and related neurodegenerative diseases.


Sevinç Jakab, PhD - Postdoctoral Fellow in Neuropathology

Sevinç joined the Seeley lab as a postdoctoral scholar in October 2023. She completed her B.Sc. degree in Molecular Biology and Genetics at Boğaziçi University in Turkey. She then moved to Germany, where she earned her M.Sc. degree in Developmental and Stem Cell Biology from Heidelberg University. Her Master's thesis focused on establishing culture conditions for circulating tumor cells from breast cancer patients in the lab of Andreas Trumpp at the German Cancer Research Center. Driven by an interest in neuroscience, Sevinç pursued a Ph.D. in the laboratory of Joachim Wittbrodt at Heidelberg University, concentrating on the role of glycosylation during retinal development. Her Ph.D. thesis demonstrated that hypomorphic mutations in the N-glycosylation machinery lead to selective cell death in the vertebrate retina. Currently, her research aims to elucidate the mechanisms of TDP-43 pathology in the brains of FTD and ALS patients carrying the C9orf72 hexanucleotide repeat expansion.


Lily Talley – Staff Research Associate

Lily joined the Seeley Lab in September 2023 as a research associate and assists with the brain bank, immunohistochemistry, and other technical work for various projects. Lily received a B.A. in Molecular and Cell Biology from the University of California, Berkeley in May 2023. As an undergraduate, Lily was a research assistant for a lab studying the neural pathways of feeding behavior in Drosophila, along with working in public health, sexual health education, and sexual violence and harassment prevention.


Felipe Luiz Pereira, PhD – Bioinformatician

Felipe is a Bioinformatician with a Computer Science background. He received his Ph.D. degree at Minas Gerais, Brazil, in 2019. In his Ph.D. thesis, he studied host-pathogen interaction in important zoonotic fish-pathogenic bacteria. He had experience as a teacher assistant in Programming Languages and Software Engineering and he worked in the National Reference Laboratory of the Brazilian Ministry of Agriculture using different types of omics technologies, such as transcriptomics and proteomics. His main interest is to integrate data from different technologies and work with big data science. He has begun as a Bioinformatician in Profs. Grinberg and Willian Seeley’s labs on May 1st of 2021, and his efforts are linked to Single Nuclei/Bulk RNA sequencing data processing, data integration, and statistical analysis.


 

Thomas Silva – Staff Research Associate

Thomas joined the Seeley Lab in July 2024 as a research associate working primarily in the brain bank. He earned a B.S. in Biological Sciences and a B.A. in Natural and Applied Sciences from Florida International University in Miami in May 2024. As an undergraduate, Thomas conducted research in a biochemistry lab, where he studied the effects of toxic levels of manganese, an environmental toxicant, on RNA synthesis by DNA polymerases. Additionally, he spent a summer researching non-invasive sensory stimulation as a potential therapeutic approach for brain-gut axis disruptions, which may have applications in Alzheimer’s disease and Parkinson’s disease.


Bianca Gonzalez – Laboratory Assistant

Bianca joined Seeley Lab in July 2024 as a laboratory assistant and assists the brain bank in the preparation and packing of fixed tissue slides along with other tasks. Bianca received her B.S. in Biology at the University of San Francisco in 2023, where she assisted in pollination research in Suni Lab focusing on the correlation between the nutritional value of pollen grains in native San Francisco and Marin County plants and pollinator frequency.
