Biswa Ramani
Graduate Student
Phone: (734)615-6156
E-mail: Biswarathan.Ramani@ucsf.edu
Biswa was a MD/PhD student who defended his thesis in 2015 in the Neuroscience Graduate Program. He explored the pathogenic mechanisms underlying SCA3, which is caused by an abnormal polyglutamine expansion in ataxin-3. His work sought to determine the mechanisms by which mutant ataxin-3 accumulates and aggregates in the brain, using a novel knock-in mouse model of SCA3. He also identified aberrant transcriptional changes that may contribute to toxicity in SCA3. He is currently a neuropathology resident at UCSF.
Bo Wang
Graduate Student

E-mail: makiwang@med.umich.edu
BBo Wang was a MD/PhD student who defended his Neuroscience Graduate PhD thesis in 2015. His dual degree is with Shanghai Jiao Tong University where he is now completing his medical degree work. Bo studied the in vivo function of Ube2W, an E2 ubiquitin conjugating enzyme that uniquely links ubiquitin to the amino-termini of proteins rather than to internal lysine residues. He generated and characterized Ube2W knockout mice, in the process establishing that this unusual E2 is important in a variety of tissues. He also explored the role of Ube2w in regulating the neurodegenerative disease protein in Huntington disease, Htt. He is currently a dermatology resident at the University of Michigan.

K. Matthew Scaglione, PhD
Postdoctoral Fellow
Phone: (314)322-3594
E-mail: matt.scaglione@duke.edu
The maintenance of proper protein quality control in the neuron is essential for proper neuronal function. Dr. Scaglione’s research involved identifying the mechanism that the protein quality control ubiquitin ligase CHIP (C-terminus of Hsc70-interacting protein) utilizes to facilitate the ubiquitination of chaperone bound substrates. Dr. Scaglione had a second project that focused on determining the biological role of specific ubiquitin chain linkages. Dr. Scaglione's work in the lab was funded in part by a K99 Pathway to Independence Award through the NIH. In August 2013, Matt began a tenure track assistant professorship at the Medical College of Wisconsin, Milwaukee, and in 2018 moved to join the faculty at Duke University, where he continues his work on ubiquitin pathways begun as a postdoctoral fellow in the Paulson lab.

Based on his findings that ATXN3 activity is carefully regulated in cells, Dr. Todi expanded his research to other deubiquitinating enzymes. Dr. Todi's work in the lab was funded by grants from the Nations Ataxia foundation and a K99 Pathway to Independence Award through the NIH. In 2010, Sokol joined the Pharmacology faculty at Wayne State University where he is now an associate professor.

As a student, she studied protein aggregation and protein quality control in mouse models of SCA3 (a.k.a Machado-Joseph disease). Aislinn's studies investigated how protein misfolding and aggregation contribute to neuronal dysfunction in neurodegenerative diseases. Aislinn successfully competed for a Predoctoral NRSA fellowship when performing her thesis work. After receiving her MD/PhD degrees in 2009, Dr. Williams completed Psychiatry residency at the University of Michigan, and joined the faculty at Iowa as an assistant professor in psychiatry and neuroscience.
Brett Winborn
Graduate Student
The complexity of the ubiquitination pathways is emerging, and Brett studied how this complexity is regulated. In his thesis work, he determined that the neurodegenerative disease protein ataxin-3 is a deubiquitinating enzyme that edits topologically complex ubiquitin chains. His main project was to decipher the biochemical properties of ataxin-3, such as its ubiquitin binding and protease activities. Brett also worked to identify the role of ataxin-3 in the cell, especially relating to pathways of ubiquitin-dependent protein degradation.
Update: After Brett completed his PhD in cellular and molecular biology at Iowa in 2009, Brett became a Postdoctoral Research Associate at St. Jude Children’s Research Hospital in Memphis, Tennessee, working with J. Paul Taylor. His current e-mail address is brett.winborn@gmail.com
