Our research interests focus on defining the roles and the mechanisms of enzymes and other challenging proteins in complex biological processes and on developing technologies to facilitate these studies. Current research in the lab is on the chemical biology of post translational modifying enzymes, receptors and membrane transporters. A particular emphasis of our work is on identifying the roles and regulating the activity of proteases and degradative enzyme complexes associated with infectious diseases, neurodegenerative diseases and cancer. We are also developing novel methods to biophysically characterize challenging proteins as well as their complexes. These studies coupled with our global substrate profiling, antibody engineering and noninvasive imaging efforts are providing a better understanding of both the chemical make-up and the biological importance of these critical proteins to aid in the rapid detection, monitoring and control of disease.

I received my BA in Chemistry concentrating in Biochemistry from Bryn Mawr College. During my undergraduate, I researched the biophysical properties of a human derived peptidic hydrogel for potential applications in medical therapies with Karin Åkerfeldt at Haverford College. My research in the Craik Lab focuses on the host pathogen interface and creating chemical tools to study dynamic protein protein interactions.

I received my B.S. in Chemistry from Allegheny College working under Dr. Ivelitza Garcia. My undergraduate research focused on DEAD-box proteins, specifically the kinetics and thermodynamics of ATP hydrolysis and RNA binding. While pursuing my PhD in the Craik Lab, I am interested in designing tools for tracking and quantifying biological events utilizing protease-activated probes. Currently, I am developing restricted-interaction-peptides for monitoring immune-activation within the tumor microenvironment with the goal of developing non-invasive biomarkers for tracking responses to cancer immunotherapies.

I received my MSc in Biology from Roma Tre University, and a PhD in Molecular Medicine from RCSI with Maria Marino and Bryan Harvey, studying the molecular changes associated with steroid signaling in endocrine-dependent tumors. My postdoc training at UCD started with Joe Duffy in the MTCI Consortium to investigate therapeutic targets for triple-negative breast cancer, then in the lab of Liz Ryan and Glen Doherty to work on resistance to targeted therapy in colorectal cancer. I joined the Craik lab in 2016, applying a protease profiling strategy (MSP-MS) to discover proteolytic signatures associated with colon cancer subtypes and progression. I collaborate with Alaunus Biosciences (co-founded by Craik) to leverage the unique protease activity signatures in the tumor microenvironment for development of protease-based diagnostic and therapeutic biomarkers. My interest broadly lies in translational research applied to oncology, at the intersection of the academic and entrepreneurial worlds.

I received my BA in Chemistry from Kyung Hee University (Seoul, South Korea) and PhD in Chemistry from the University of California, Davis. My PhD research focused on deciphering the mechanism of how substrate and reaction specificities are controlled in two classes of enzymes, chorismate utilizing enzymes and PLP-enzymes. I developed a novel multi-site-specific mutagenesis method to assist in a bioinformatics tool Janus, where key residues predicted to be important for substrate and reaction specificity were randomly mutated. Currently, I am interested in designing next generation phage displayed fab libraries for the rapid identification of high affinity Fabs against specific conformations of transmembrane proteins, proteases involved in various cancers, and DNA. With newly discovered Fabs, I hope to elucidate new fab-target interactions and further utilize them for various applications.

I received my BS in development biosciences and my Msc in pathology from the Fluminense Federal University (Rio de Janeiro, Brazil). During my PhD I focused on the development of Restricted-Interaction Peptides (RIPs) for the non-invasive imaging of threatening blood clots in vivo through near-infrared (NIR) fluorescence and positron-emission tomography (PET). My research interests lie in the understanding of disease-associated proteolysis, particularly in cardiovascular diseases and cancer, to proper optimize our RIP technology toward clinical translation.

I received my BA in Chemistry at The College of Wooster in 2016. My undergraduate research focused on the development of synthetic methods for the chiral control of the Ugi multicomponent reaction. In my graduate research, I am interested in the development of safer therapeutics for cancer. Specifically, I am using our recently developed MSP-MS technology for the global characterization of misregulated proteolysis in breast cancer to enable the development of protease activated prodrugs. Additionally, I am interested in using antibody engineering approaches for the development of safer immunotherapies.

I received my BS in Chemistry from Whitworth University. During this time I conducted biochemical research on enzyme therapeutics with Prof. Deanna Ojennus, and biophysical research on transmembrane proteins as an Amgen Summer Scholar. I then earned my PhD degree from UC Berkeley, under the guidance of Matthew B. Francis, where I conducted research on the characterization and application of protein bioconjugation reactions. Here, in my postdoctoral studies, I am using a combination of chemical, biochemical, biophysical, and structural biology techniques to identify, characterize, and optimize therapeutic viral protease inhibitors.

I graduated from Penn State with a BS in Chemistry. While there, I worked with Dr. Joseph Cotruvo Jr. on the development of RNA-based fluorescent probes for the detection of transition metals in vivo. After receiving my BS, I worked as a Postbaccalaureate Fellow at the National Institute of Mental Health with Dr. Victor Pike. My research focused on the development of a 11C-trifluoromethylation methodology with an application to developing radiotracers for positron emission tomography (PET). For my graduate work in the Craik Lab, I am interested in the development of diagnostic tools and therapeutics utilizing disease-associated proteolysis.

I am a general surgery resident at UCSF currently completing a two-year research fellowship under the mentorship of Dr. Kimberly Kirkwood. I am working with Dr. Kirkwood on both translational and health services research projects to validate targets for improved diagnosis and surgical outcomes in pancreatic cystic and solid lesions. Specifically, we are identifying patterns of uPAR expression in pre-malignant pancreatic cysts that may be exploited for diagnosis, risk-stratification for progression to pancreatic adenocarcinoma, and treatment.

I graduated with a BS in Molecular, Cellular, and Developmental biology from Yale University. There, I worked at the Yale Stem Cell Center with Dr. Haifan Lin to investigate how the Piwi protein regulates proper stem cell proliferation and differentiation in Drosophila. After receiving my BS, I worked as a Postbaccalaureate Research Fellow at the SENS Research Foundation with Dr. Amit Sharma. I am Dr. Kirkwood’s clinical research coordinator for her studies examining pancreatic cysts. I enroll patients in PANC Cyst, an e-registry for patients with pancreatic cysts, as well as a national ECOG-ACRIN clinical trial to examine surveillance strategies for patients with pancreatic cysts. I collect pancreatic cyst fluid from patients undergoing endoscopic ultrasounds and surgeries at UCSF to be used for protease research by various members of the Craik Lab.

Daisy Valdivieso I received my B.S. in Molecular Environmental Biology from the University of California, Berkeley. After graduating, I began working as a clinical research coordinator for two large COVID surveillance studies tracking incidence and prevalence across the six Bay Area counties and in healthcare workers in 3 hospital systems. Since the conclusion of those studies, we are now tracking breakthrough infection in a subset of that cohort. In addition to my work staffing testing sites and interfacing with participants, I also biobank specimens collected from the testing sites. My work in the Craik Lab involves investigating ACE2 and neutralizing antibodies with variant spike protein from SARS-CoV-2.

After leaving the Craik Lab, people continue their careers in research and education in a wide variety of ways. They continue learning, teaching, and doing science, often as leaders in their fields, whether in the Bay Area, California, the United States, or internationally. They take with them the many experiences they gathered during their time at UCSF.
