Wayne S. Zundel, Ph.D.

Director, Division of Molecular Radiation & Cancer Biology

Dr. Zundel obtained his BS in Chemistry from Montana State University in a three year period. He obtained his Ph.D. in Cancer Biology in Amato Giaccia's laboratory at Stanford also within three years. Dr. Zundel  has held scientific positions in the federal government and within the pharmaceutical industry prior to academic appointments. He serves on various national and international grant study sections and has been an invited speaker at various international events such as Keystone Symposia, AACR Workshops and Gordon Conferences.

Dr. Zundel studies the lack of oxygen (hypoxia) primarily in cancer progression and therapeutic response but also looking for applications in other ischemic pathophysiologies such as  pulmonary disorders, aging, cardiac and vascular disorders, diabetes, infection, obesity, and various other aging-related disorders. The Zundel laboratory examines the molecular mechanisms by which altered extracellular oxygenation mediates diverse effects in mammalian tissues. These responses are serendipitously uncovering novel aspects of basic cellular functions, such as energy metabolism, protein turnover by ubiquitylation, translational arrest, IRES-mediated translational initiation, mRNA stability, and the stem cell biology. A combination of functional genetics, genomics, and proteomics is utilized to examine the molecular architecture underlying oxygen-sensing and response mechanisms. By defining the molecular responses to hypoxia, it will be possible to target these regulatory pathways with greater specificity. This will ultimately lead to the identification of stage-specific diagnostic and prognostic markers and the development of novel therapies that manipulate these processes.

Jing Huang, MBA, PhD

Research Associate & Lab Manager, Radiation Medicine, OHSU

Jing was born and raised in Northeast China and moved to Oregon for graduate school in 1992 and received her doctorate degree in Genetics from Oregon State University in 1998. During her first postdoctoral fellowship, she studied several proteins involved in the G1/S and G2/M checkpoints in Matt Thayer's lab at The Vollum Institute, OHSU.   Jing has also had extensive training using diverse clinical  & translational approaches while conducting research in Elliot Epner's and Craig Okada's labs at OHSU. From 2004-2008, Jing entered the biotechnology industry as a staff scientist at ProteoGenix Inc. & during this time gained an MBA in Finance from Portland State University. She says that her experience in the business aspect of the biosciences has expanded her mindset in general toward the applied sciences.

Since joining the Zundel Lab., Dr. Huang has begun a systematic exploration of oxygen-responsive cellular processes & is currently developing models that differentiate patterns in hypoxic & ischemic gene regulation allowing her to distinguish oxygen-regulated responses in different tissues, stages of oncogenic progression and non-oncogenic ischemic pathologies. Within this framework (jokingly dubbed the Hypoxeome), she is identifying critical non-redundant signaling nodes & characterizing the molecular roles of the proteins in the context of altering specific hypoxic/ischemic phenotypes during tumor progression or enhancing current therapeutic methodologies.

During Jing's spare time, she enjoys spending time with  her family, taking classes in the gym, watching local & national news & sports, & keeping current on the Wall Street Journal, Financial Times, and Fortune magazine.

Peter Mikus, Ph.D.

Postdoctoral Fellow

Current position unknown

Dr Mikus was born in Slovakia (the former Czechoslovakia).  After graduation from Comenius University, he worked for several years at the Slovak Academy of Sciences.  Peter also spent some time as a visiting researcher at Umea University in Sweden and at Stanford University. Peter then moved to Sweden where he obtained his Ph.D. at Umea University.  For postdoctoral training, he moved to UC Berkeley at the Gladstone Institute of Cardiovascular Disease and at UCSF.  His training and broad research experience allowed him to work on many different projects, from classical biochemistry to various areas of cell and molecular biology and new -omics approaches. Dr. Mikus was then recruited to the Zundel lab at the J.G. Brown Cancer Center in Louisville, KY.   Here, Peter became involved in studies of protein functions and interactions in the context of complex molecular networks.  Dr. Mikus spent 6 months in the lab of Marc Vidal && David Hill at the Dana Farber Cancer Institute performing high-throughput yeast-2-hybrid (HT-Y2H) on hypoxia -regulated genes, thus laying the groundwork for the "hypoxeome" which is a major portion of ongoing research in the lab.

Tatulya "Joey" Tawari, M.D.

Lab. Technician

Currently in private practice.

Joey was born in Gwalior, India and immigrated to the United States of America in 1988, at the time he was six years of age.  Joey resided in Louisville, Kentucky since that time and attended Michigan State University as an undergraduate.  In December of 2003, he graduated from MSU with honors and earned a B.S. in Microbiology and Molecular Genetics.  Before getting involved in research, Joey enrolled in an Environmental Studies program in Costa Rica as part of a study abroad through MSU.  This experience sparked a research interest in plant biology. 

Joey was privileged to conduct research for two years in Dr. Katherine Osteryoung's laboratory as an undergraduate. The primary goal of that laboratory is to identify and investigate proteins critical to chloroplast division.  Joey's project goals included insertion of an inducible promoter system over-expressing T-DNA of critical plastid division proteins into the Arabidopsis thaliana genome. Some of his other projects involved sequencing of genomic DNA of transgenic plants as well as for AtMinD, a protein critical to division site selection. In May of 2004, Joey was awarded a prestigious Fogarty International Research Fellowship administered by the National Institute of Health to conduct biomedical research at an over-seas training institution.  Joey carried out research in Grenoble, France under the direction of Dr. Michael Haertlein and the Institut Laue-Langevin in collaboration with the European Molecular Biology Laboratory. This project enabled Joey to provide evidence for plasmid instability in isotopically (deuterated) labeled E.coli cells.

Mr. Tiwari  then joined the Zundel lab where he briefly worked on validating novel interactions of putative proteins in the oxygen sensing pathway of mammalian cells that are linked to formation of cancer. Joey then moved to a collaborator's lab at Stanford (Nic Denko) where he studied hypoxia-inducible genes. Joey was accepted into medical school at the University of Louisville where he recently graduated. Aside from his research experience, Dr. Tawari teaches and coaches tennis to players that range in experience from novice to nationally ranked.  His other hobbies include hanging out with his family and going to see movies on the weekend.
