Lev Tsypin
Postdoctoral Scholar, Pathology
Current Research and Scholarly InterestsI am working with Botryococcus braunii, a species of freshwater microscopic algae. This organism is unique among plants in that it secretes copious amounts of oil that is chemically analogous to petroleum. This organism may be the key to developing a cheap and sustainable alternative to fossil fuels, but we do not yet have the tools to engineer or optimize its oil production. My work aims to bridge this gap.

Xun Tu
Postdoctoral Scholar, Psychiatry
Current Research and Scholarly InterestsAs a postdoctoral fellow in Dr. Erin Gibson’s lab, I am integrating my expertise in molecular signaling and systems neuroscience to study the role of OPCs in sleep. My interest in sleep has been further reinforced by observing the dramatic shifts in sleep architecture across developmental stages as a new parent, highlighting the necessity of sleep for neural refinement. My current research uses in vivo calcium imaging and closed-loop optogenetics to determine how OPC-neuron communication coordinates hippocampal sharp-wave ripples. By characterizing how aging blunts OPC responsiveness to sleep, I aim to identify novel strategies to preserve memory and promote healthy cognitive aging.

Mirko Uljarevic
Affiliate, Psychiatry and Behavioral Sciences - Child & Adolescent Psychiatry and Child Development
BioI am a medically trained researcher focused academic with a background in developmental psychopathology, psychometrics and big data science. My research takes a life-span perspective and is driven by the urgent need to improve outcomes for people with autism and other neuropsychiatric (NPD) disorders and neurodevelopmental conditions (NDD). My primary research interest has focused on combining cutting-edge psychometric procedures and a big data approach to better understand structure of clinical phenotypes across autism and other NPD and NDD and on using this knowledge to improve existing and develop new clinical assessments that are more effective for screening and diagnosis, tracking the natural and treatment-related symptom progression and for use in genetic and neurobiological studies. In addition to my focus on the development of outcome measures, I have collaborated with leading psychopathology researchers and groups in the United States, Europe and Australia on numerous projects spanning a range of topics including genetics, treatment and employment, with a particular focus on understanding risk and resilience factors underpinning poor mental health outcomes in adolescents and adults. Most recently, through several competitively funded projects, I have led the statistical analyses to uncover the latent structure of social and communication and restricted and repetitive behaviors (RRB) clinical phenotypes across NPD and NDD. These findings have enabled us to (i) start capturing and characterizing a highly variable social functioning phenotype across a range of disorders and understanding mechanisms underpinning this variability, (ii) combine phenotypic and genetic units of analyses to advance our understanding of the genetic architecture of RRB, and (iii) focus on identification and characterization of subgroups of individuals that share distinct symptom profiles and demonstrate clinical utility and neurobiological validity. Importantly, this work has provided key information for developing a programmatic line of research aimed at developing novel, comprehensive assessment protocols that combine parent and clinician reports, objective functioning indicators and incorporate state-of-the-art psychometric, mobile and connected technologies and procedures.
I am a co-director of the recently established Program for Psychometrics and Measurement-Based Care (https://med.stanford.edu/sppmc.html) that aims to bring together world-leading expertise in clinical science, psychometrics, and big data analytics to bridge the gap between the science of measurement development and clinical practice and bring improvements to both clinical care and research. -

Sivakamasundari V
Instructor, Institute for Stem Cell Biology and Regenerative Medicine
BioMy research interests are focused on understanding the molecular basis of early development and stem cells, as it is often aberrations in stem cells or signaling mechanisms between tissues that lead to diseased states, including tumor development and cancer progression. Knowledge of stem cells and development is also critical to develop appropriate cell-based therapies for various diseases or injuries. My prior and current works take advantage of both traditional techniques (gene targeting, lineage tracing) and state-of-the-art technologies (Single cell RNA sequencing, Chromatin Immunoprecipitation (ChIP-seq), Imaging Mass Cytometry) to elucidate fundamental molecular mechanisms underlying signaling in tissue biology.
