Norma Morella, Ph.D. / Co-Chair
Pivot Bio
Norma Morella, Ph.D. / Co-Chair
Pivot Bio
Norma Morella earned her doctorate in Microbiology from UC Berkeley where she studied the plant microbiome. Her work explored which factors can shape host-associated microbial communities, from host genotype to bacteriophages (viruses that infect bacteria).
Norma received a WRF Postdoctoral Fellowship in 2020 and moved to Seattle to conduct her research at Fred Hutchinson Cancer Center. While at Fred Hutch, Norma investigated the complex interplay between gut bacteria, carcinogenic compounds that they produce, and bacteriophages. This work contributes to our growing understanding of how phages might be used as therapeutic tools to modulate microbial communities for human health. Currently, Norma works as a research scientist for Pivot Bio, a Berkeley-based biotech company that is replacing synthetic nitrogen fertilizer in agriculture with a nitrogen-fixing bacterial product. Norma previously served on the Executive Board for SoundBio Lab, a nonprofit biology makerspace in Seattle, and she is an active member of Women in Bio’s Seattle Chapter.

Washington State University
Cliff Berkman, Ph.D.
Washington State University
A major area of the research in my lab is aimed at the development of biomarker-targeted small-molecule conjugates as radio-diagnostic, radio-therapeutic, and chemotherapeutic agents. Most notable are our agents targeted to the prostate cancer enzyme-biomarker known as prostate-specific membrane antigen (PSMA). In addition, we have focused on the development of pH-responsive cleavable linkers for controlled release applications. We are also interested revealing the biological consequences of non-canonical phosphorylation [e.g., phospholysine (pLys), phosphoglutamate (pGlu), phosphoaspartate (pAsp)] by kinases and xenobiotic organophosphorus toxicants, especially with respect to the formation of traceless isopeptide crosslinks in proteins that may occur as a result.

Kanako Hayashi, Ph.D.
Washington State University
Kanako Hayashi, Ph.D.
Washington State University
Dr. Hayashi is a Professor at the School of Molecular Biosciences, Washington State University (WSU). Prior to joining WSU. Dr. Hayashi was an Associate Professor at Southern Illinois University School of Medicine (SIUSOM). Dr. Hayashi received her B.S and M.S at Obihiro University in Japan, and her Ph.D. at Iwate University in Japan, mainly studying ovarian functions. She conducted postdoctoral research in Drs. Bazer/Spencer’s Lab at Texas A&M University, where she studied uterine biology to understand the molecular mechanisms regulating uterine gland development and implantation. After she became an independent researcher at SIUSOM, she further expanded her research focus to gynecological diseases, such as ovarian and uterine cancer and endometriosis, and reproductive toxicology.
The primary focus of Dr. Hayashi’s lab is to understand pathogenesis and pathophysiology in endometriosis. Endometriosis affects approximately 10% of reproductive-aged women, but there are no biomarkers and no cure, and the mechanisms of this disease remain unclear. As it is a chronic inflammatory disease, we study the mechanisms of immune cell contribution to disease establishment and progression and how it can cause endometriosis-associated chronic pain, including central sensitization and neuroinflammation. We also develop non-hormonal therapy to target pro-disease macrophages for the treatment of endometriosis and its associated chronic pain. Additionally, we study how maternal exposure to environmental factors, such as endocrine-disrupting chemicals and cannabis, affects reproductive functions and germ cell development in the next generations.

Harmit Malik, Ph.D.
Fred Hutchinson Cancer Center
Harmit Malik, Ph.D.
Fred Hutchinson Cancer Center
Dr. Harmit Malik studies genetic conflict, the competition between genes and proteins with opposing functions that drives evolutionary change. His research could have implications for a range of diseases, from HIV to cancer. As part of this work, his team developed an approach for identifying genes that divide one species from another, which could help solve the riddle of how new species evolve. Dr. Malik also studies the evolutionary processes that drive our body’s interactions with viruses, including contemporary scourges like HIV as well as ancient viruses whose fossils litter our genome. With Hutch colleagues, he has characterized the rapidly evolving interface between proteins on human cells and viruses that make us sick. This work has highlighted surprising deviations from “textbook” models of these interactions, and it is revealing gene variants that could influence our susceptibility to infection.

Aakanksha Singhvi, Ph.D.
Fred Hutchinson Cancer Center
Aakanksha Singhvi, Ph.D.
Fred Hutchinson Cancer Center
Dr. Aakanksha Singhvi studies glial cells, which are critical to the correct functioning of our nervous system. Every time a neuron connects to another neuron, a glial cell is there to make sure that signals transmit properly between them. Glia themselves also communicate with neurons and influence their shape and activity. Disruptions in communication between neurons and glia underpin many neurological disorders, including Alzheimer’s and autism. Dr. Singhvi seeks to understand the molecules involved in glia-neuron communication, and how glia influence neuron shape and function, and, ultimately, animal behavior.

Jonathan Ting, Ph.D.
Allen Institute
Jonathan Ting, Ph.D.
Allen Institute
Jonathan T. Ting joined the Allen Institute in 2013 to provide electrophysiology expertise for the Human Cell Types program and to develop functional assays on human ex vivo brain slices. Ting has 15 years of experience in patch clamp electrophysiology encompassing both primary neuron cultures and acute brain slices. In his postdoctoral fellowships at Duke University and the McGovern Institute for Brain Research at MIT, he studied the neural circuitry basis of psychiatric disorders and developed and characterized several transgenic mouse lines now widely employed for optogenetic control of nervous system function. Ting previously earned a Ph.D. in Neurobiology & Behavior and conducted his thesis research in the Department of Physiology & Biophysics at the University of Washington School of Medicine in Seattle. He earned a B.S. in Biological Sciences with emphasis in Neurobiology, Physiology and Behavior from the University of California at Davis.
Research focus: A comprehensive analysis of the architecture and function of the human brain requires a multifaceted strategy for revealing the true complexity and diversity of cell types that reside within. It is the exquisite and complex assembly of these unique cell types into distinct functional circuits that enables us to perform essential tasks such as sensory perception, coordinated movement, cognition, and more. Although much effort has been devoted to anatomical mapping of the human brain using post-mortem tissue in both health and disease, the detailed analysis of functions subserved by individual cells within the living human brain has been more challenging to explore. To achieve this goal, we have established extensive research collaborations with local neurosurgeons in the greater-Seattle area to routinely obtain neurosurgical samples of human cortex for research purposes. The vital human brain tissue is transported to the Allen Institute and sectioned into brain slices for detailed analysis using diverse methodologies including patch clamp electrophysiology, optical imaging, single cell transcriptomic profiling, morphological reconstructions, and array tomography. We hope this effort will culminate in a comprehensive classification of cell types of the human neocortex.
