Dr. Eric Yale Hayden is an Assistant Project Scientist in the David Geffen School of Medicine at UCLA, and Brain Research Institute. Dr. Hayden was recognized for his research by receiving the Southern California Alzheimer's Association Young Investigator Award in 2013. Previously, he earned first place postdoctoral researcher in the UCLA Neurology Science poster day, a department consistently ranked #1 or 2 in the nation based on NIH funding. He has a long held interest in understanding protein folding and misfolding, and specifically, its relation to neurodegenerative diseases, including Alzheimer's and Parkinson's disease. He distinguished himself early on by conducting research in high school for which he was selected as a national Semifinalist in the 2000 Intel Science Talent Search. Dr. Hayden’s doctoral thesis focused on studies of the molecular basis for the fibrillation of a-Synuclein, the protein found aggregated into amyloid fibrils in Lewy bodies in Parkinson’s disease (PD) neurons, by using various spectroscopic and analytical methods. He also collaborated widely, including work with an organic chemist, developing small molecules and testing them as drug candidates for possible detection, prevention and/or therapy for PD or Alzheimer’s disease. He currently works with Dr. David Teplow to better understand structure and neurotoxicity relationships of Aβ oligomers.

Dr. Mikhail Kibalchenko is a postdoctoral fellow who is an expert in quantum mechanics and its implementation in understanding protein structure and dynamics. He has combined quantum mechanics with experimental techniques as a powerful interdisciplinary tool to progress scientific knowledge in the structural studies of infinitely disordered chalcogenide glasses, magnetic environments within carbon nanotubes, techniques for distinguishing hydrogen bonding networks, and most recently transport mechanisms in the ADP/ATP mitochondrial transport proteins. In the Teplow laboratory Dr. Kibalchenko is studying the mechanisms of pathogenesis of Alzheimer’s Disease.

    Postgraduate Researcher
  • B.S., Neuroscience, UCLA, 2015

Joseph L. Conovaloff graduated magna cum laude from UCLA with College Honors and Departmental Honors in June 2015 with a bachelor of science in neuroscience and minors in biomedical research and Russian language. Upon graduating, Joseph was inducted into Phi Beta Kappa, the oldest honor society in the United States. He began working in the Teplow laboratory in June 2012 and worked with Dr. Eric Y. Hayden to develop an efficient and successful method of isolating individual oligomers of the amyloid beta-protein. He is now working to characterize these oligomers through various biochemical and biophysical characterization studies. As an undergraduate at UCLA, Joseph participated in many research activities, including the Howard Hughes Undergraduate Research Program, which identifies students who show great promise in the biomedical sciences. For three years, he worked on the Undergraduate Science Journal (USJ) Editorial Board, peer-reviewing research and review articles submitted by undergraduates at UCLA for which he was the Editorial Managing Editor in his senior year. Joseph has won several scholarships and awards for his work, including the UCLA Dean’s Prize as a second-year undergraduate, and he was named a UCLA Undergraduate Research Senior and Junior Scholar. He continues to present his work regularly. Currently, he is a teaching assistant for the UCLA Biomedical Research Minor.

    Undergraduate Researcher

Parvaneh Shadkam-Farrokhi is a third year undergraduate student majoring in Neuroscience and minoring in Biomedical Research at UCLA. She began working in the Teplow Laboratory in February 2014 and is currently working with Dr. Eric Y. Hayden to develop a pathological biomarker for Alzheimer’s Disease by examining cerebrospinal fluid effect on Aβ42 oligomers. She hopes that her research can one day be used to develop an assay system to measure the development of Alzheimer’s Disease and to allow for the early diagnosis of familial Alzheimer’s Disease. Aside from performing research in the Teplow Laboratory, Parvaneh works as a Lab Assistant creating experimental kits for the joint California NanoSystems Institute and IGERT Materials Creation Training Program (MCTP)’s High School Nanoscience Program, allowing high school students to gain exposure to the field of nanoscience involving self- assembly, supercapacitors, solar cells, photolithography, super hydrophobic surfaces, and biotoxicity.

    Undergraduate Researcher

Pei-Yun Tseng is a fourth year undergraduate at UCLA, majoring in Biochemistry. Her curiosity in protein structures lead her to the lab of ZheFeng Guo during the summer of 2015 to study Yeast Prion morphology using Electron Paramagnetic Resonance. She also examined the aggregation of Amyloid-β protein, which lead to her interest in studying the proximate pathogenic agent, amyloid-β oligomer structures in the Teplow Lab. Under Dr. Eric Y. Hayden’s guidance, she is currently working on understanding the structure-activity relationships of Aβ42 oligomers of specific order.
