Max is a senior research associate at General Proximity continuing his work on protein-protein interactions and helping to design and test new bifunctional molecules for use in clinical applications. Outside the lab, you’ll see Max biking, sailing, or climbing around the bay!

Edward Morris

Edward completed his undergraduate degree at Canterbury University in New Zealand and his PhD in Pathology and Cell Biology at the Columbia University College of Physicians and Surgeons, working in the lab of Dr. Gregg Gundersen. There he worked on how the cytoskeleton regulates cell migration and invasiveness.

Edward completed his postdoctoral studies in cancer drug development at the British Columbia Cancer Research Centre, working on a novel role for the oncogene Stat3 in mitosis. Edward led a high-throughput screening program based on automated scoring of centrosomes in mitotic cells to identify drug candidates that specifically disrupt the way many cancer cells divide while crucially sparing normal cells. This research program, in collaboration with industry partners, identified a Stat3-targeting compound that specifically inhibits cancer cells with aberrant cell division. Edward is currently working as a scientist on the Biology team at General Proximity where he is identifying new leads to develop into bifunctional molecules. Outside of work, he can be found at the park or in a museum with his 2-year old.

Veronika Shoba

Veronika Shoba completed her PhD in Chemistry at the University of Nebraska-Lincoln under the supervision of Dr. James Takacs. In her PhD thesis work, Veronika studied oxime-directed catalytic asymmetric transformations and discovered reaction conditions for highly substituted olefins with formation of unprecedented hydroboration and hydrogenation products. After completing her PhD and a brief stint at Genentech, Veronika joined Amit Choudhary's lab at the Broad Institute of MIT and Harvard as a Damon Runyon Fellow.

While at Broad, Veronika designed and synthesized first-in-class phosphorylation-inducing bifunctional small molecules (PHICS) that enabled kinases to introduce known and novel phosphorylations on the target proteins. These proof-of-concept studies demonstrated that induction of proximity between kinase and protein-of-interest can lead to therapeutically relevant functional outcomes. Veronika is now a scientist at General Proximity, supporting the platform team, prioritizing targets, and exercising her experience in proximity-induction by designing and testing new molecules. In her free time, Veronika likes kayaking, watching stand-up comedy, reading fiction, searching for “the best Ramen place,” and exploring various art exhibits.

Ernesto Diaz-Flores

Ernesto Diaz-Flores, a cancer biologist and biochemist from the University Complutense (Madrid), completed his PhD in Molecular Biology at Universidad Autonoma (Madrid) where he studied the signaling role of protein kinase C in T cell activation. He then moved to San Francisco to pursue a postdoctoral training in the laboratory of Dr. K. Shannon at UCSF, where he performed extensive multiparametric flow cytometry studies to study the signaling rewiring induced by mutant KrasG12D and NF1 in Acute Myeloid leukemia. His studies were instrumental in identifying druggable vulnerabilities with therapeutic potential, an achievement recognized by the Children’s Tumor Foundation who awarded him the Young Investigator Award. He then joined Dr. M. Loh for further postdoctoral training in childhood B cell leukemia. In 2013, he and his team published a seminal publication in Nature Genetics where he led the discovery of inherited mutations in TP53, including new variants, in hypodiploid leukemia, which is now used in the clinic to screen relatives of these patients in search of Li-Fraumeni syndrome. These findings demonstrating the role of mutant p53 as initiating event at diagnosis in the absence of concurrent mutations shed new light into the oncogenic relevance of this gene in cancer.

In 2014, Ernesto obtained a faculty position as an Assistant Professor in the UCSF Pediatrics Department. As a professor, Ernesto’s work focused on elucidating how genetic alterations associated with poor prognosis in cancer patients (such as TP53 and NRAS mutations and/or CDKN2A/B and IKZF2 deletions) hijack the BCL-2 survival pathway to confer therapy resistance. His lab was supported by several funding agencies such as the Leukemia Research Foundation (LRF), American Cancer Society (ACS), the Hughes foundation, Team Connor (TCCF), Cookies for Kids (C4K), and Elsa U. Pardee among others.  He was an invited lecturer at multiple institutions around the US and Europe including the American Society of Hematology, American Association for the Advancement of Science (AAAS), American Association of Cancer Research (AACR), Temple University, Centro Nacional de Biotechnology (CNB-CSIC), and others. A prolific mentor and teacher, he currently serves as a panel member for the U.S. Department of Defense’s Congressionally Directed Medical Research Program (CDMRP) and as a member of the Editorial board of “Frontiers Cell and Development Journal”. His work has been recognized by numerous awards such as the American Cancer Society Individual Research award two years in a row, the UCSF Chancellor's Faculty Resource Award, and the UCSF Faculty Learning and Development Award.

In 2019, Ernesto published a pioneering research work combining next-gen genomic sequencing and protein profiling paired with combinatorial drug screening, which demonstrated exceptional preclinical efficacy of Venetoclax in hypodiploid B-ALL patients. This led to the opening of the first clinical trial of this targeted therapy sponsored by AbbVie in the underserved patient population of children with high-risk B-cell leukemia.

In 2022, Ernesto and his team reported the identification of the first biomarker of response to Inotuzumab in relapse/refractory leukemia patients through the combination of mass cytometry and machine learning in longitudinal samples collected during the clinical trial, work that has also led to the early opening steps of another clinical trial sponsored by Pfizer for children with Relapse/Refractory B-ALL leukemia. The publication of this work was followed shortly by his promotion to Associate Professor.

Ernesto is now a Senior Principal Scientist at General Proximity where he leads the Biology Team in their efforts to advance pre-clinical assets towards the clinic.

Armand B. Cognetta III

Armand began his biotech career at the then early-stage biotech, Alnylam Pharmaceuticals, as their first intern, where he helped develop an in vivo RNAi quantification technology still in use over a decade later when Alnylam became the first company to bring an FDA-approved RNAi therapeutic to market.

 

Armand then completed his PhD in Chemical Biology at the Scripps Research Institute under the supervision of Dr. Benjamin Cravatt. There, he co-authored 19 scientific publications in prestigious journals such as Cell, Nature, and Science, as well as multiple patents, including a portion of the foundational IP for Abide Therapeutics (acq. Lundbeck, $250 M) and Vividion Therapeutics (acq. Bayer, $1.5 B).

While in the Cravatt Research Group, Armand also co-authored the development of both the first proteome-wide cholesterol and anandamide lipid binding maps, created the first platform for proteome-wide discovery of protein-protein interaction modulators, discovered a novel class of anti-tubercular drugs, synthesized the first covalent Wnt pathway activator, co-developed a novel class of endocannabinoid-potentiating therapeutics with implications for cancer, analgesia, inflammation, and Alzheimer’s, developed two drugs that reversed aging in C. elegans and mice, led an international investigation of the 2016 Bial clinical trial disaster (data arising from this presented to FDA led to a reversal of their decision to ban clinical trials in this area; in collaboration with Pfizer), and developed/synthesized multiple first-in-class covalent molecules for many previously undrugged proteins such as PNPLA4, ABHD3, CPVL, and PPT1.

Armand then joined the Flagship Pioneering start-up Inzen Therapeutics as one of the first ~five employees, where he single-handedly built the company’s proteomics drug discovery engine: the first platform enabling global mapping of novel cell-death signaling factors. After Inzen, he went through Y Combinator as a solo founder to develop the next generation of induced-proximity medicines at General Proximity, where he currently serves as Founder and CEO.

Zachary Severance

Zach completed his PhD in Biochemistry at the University of Oklahoma in the lab of Dr. Anthony W.G. Burgett. His dissertation research employed cutting-edge techniques at the interface of cellular biology, protein biochemistry, and chemical genetics to understand new cellular processes in lipid biology, innate immunity, and cell signaling. This work focused on characterizing the cellular activity of bioactive natural products targeting oxysterol sterol binding proteins (OSBP), a class of proteins emerging as attractive therapeutic targets due to their previously unrecognized roles in various diseases including cancer and viral replication. Utilizing these molecules as biological probes, he discovered critical insights into cancer and antiviral biology, including an unrecognized role in mTORC1 regulation. These insights were leveraged to develop the first OSBP-directed prophylactic broad-spectrum antiviral therapeutic approach. The evolutionarily conserved viral dependence on OSBP as a host factor indicates that this approach may be effective against viruses that have not yet emerged, and could be an important tool for rapidly combating future pandemics. For this work, Zach was awarded the Bullard Dissertation Completion Fellowship which is awarded to the top doctoral dissertations at the University of Oklahoma each year. Zach is also passionate about teaching and scientific communication, resulting in numerous teaching awards during his time at OU, including a 3x awardee of the Provost’s Certificate of Distinction in Teaching. 

After completing his Ph.D., he joined Dr. Amit Choudhary’s lab at the Broad Institute of MIT and Harvard as a Postdoctoral Associate and MIT affiliate researcher. His postdoctoral research focused on the development of new classes of bifunctional molecules using DNA-encoded library (DEL) screening. These bifunctional molecules induce synthetic proximity between an effector and target of interest to enable direct protein editing (e.g., phosphorylation), or direct recruitment of immune components to pathogens. During this time, Zach led a team of researchers in a high-impact DARPA project exploring novel proximity-induction mechanisms for targeting multidrug resistance pathogens. Working closely with the Schreiber lab, he implemented a DEL screening platform that led to the discovery of chemical matter against immune and pathogen surface proteins that were previously unamendable to bifunctional recruitment. Secondly, his postdoctoral research focused on the use of CRISPR-Cas based directed evolution to evolve proteins with enhanced functions and study drug resistance to better understand drug resistance development against bifunctional molecules compared to traditional inhibitors.

Zach is now a scientist at General Proximity where he works with the Platform and Biology Teams to help develop next generation proximity-inducing therapeutics. In his free time, Zach enjoys spending time with his family, reading, camping, sports, and horror movies.

Nicholas T. Hertz, PhD

Nicholas T. Hertz, PhD, is originally from Santa Monica, California. He graduated magna cum laude from the University of California, Los Angeles, with a bachelor’s degree in biochemistry in 2006, doing research in both a synthetic organic chemistry lab and a biochemistry lab. He then combined his research interests by performing a PhD in chemistry and chemical biology with Drs. Kevan Shokat and Al Burlingame at the University of California, San Francisco, using chemical genetic techniques to elucidate kinase signaling pathways. Dr. Hertz then conducted postdoctoral research with Dr. Marc Tessier-Lavigne at Stanford, where he identified a novel gene, Rufy3, that controls sensory axon degeneration during development.During his time in the Shokat Lab, he made the discovery that PINK1 could utilize the N6 modified ATP analog kinetin triphosphate (KTP) more efficiently than ATP. The development of novel activators to treat underactive kinases could represent a new weapon in the fight against diseases that are associated with kinase underactivity. Dr. Hertz is the founder CSO at Mitokinin, which he co-founded to develop novel PINK1 targeting therapies and recently sold to AbbVie.
