Vision Statement

I joined the AACR during my medical oncology fellowship. That same year I attended my first AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics meeting, at which Doug Hanahan first described dual VEGF and PDGF inhibition in his RIP1-Tag2 model. I approached him after his talk, asking if anyone at UCSF was following up on his findings with a clinical trial. When he said “no,” I demurely asked if he would be supportive of my doing so. He enthusiastically responded: “I’ll write a letter of support!” The investigator-initiated, NCI-sponsored trial that explored the impact of that strategy on tumor vasculature and clinical outcome in melanoma was the centerpiece of my subsequently funded K23 grant. I learned that some of the most consequential mentoring comes unexpectedly and, at times, from a distance.

I spent the first decade of my career honing my own definition of clinical-translational cancer research, sorting out how to sustain a career pursuing it. I have spent the second decade recruiting and mentoring the 25 faculty members of the Termeer Center for Targeted Therapy at the MGH Cancer Center, all of whom combine patient care, clinical investigation, and thematic research into novel therapeutics and refining biomarker-defined populations who should receive them. For this work to be scientifically grounded, multi-disciplinary team science is essential: attending collaborators’ lab meetings and collectively evolving our research strategy. This program-building required in-person, local mentoring.

My primary focus is on the development of clinical-translational investigators focused on areas of greatest unmet need: underserved populations by virtue of cancer biology and/or social determinants. Using unmet need as the organizing principle for recruiting, training, and supporting the next generation of cancer investigators, we can achieve a population-representative investigator community. Lack of clearly defined career paths and funding opportunities have diverted would-be investigators into more established disciplines with abundant funding. A new network of mentors from across the AACR community is needed.

The goal of my AACR presidency would be to ascertain and address the gaps in our clinical investigator ranks through the lens of greatest unmet need. Job descriptions are inadequately defined for trainees across oncology research who aim to pursue new research areas, particularly in community-based clinical care settings. Working with academic medical centers, community-based practices in underserved areas, and the NCI, a matrix of career descriptions with funding opportunities must be created and used as our roadmap. The AACR is the natural convener for this multi-stakeholder discussion (exemplified in the 2020 AACR Cancer Disparities Progress Report). My specific agenda is to address the misalignment between investigators’ ambition to address persistent unmet needs and available career paths.

I would like to work with trainees and early-career laboratory scientists alongside clinical investigators to create digital communities in which they share findings and hypotheses, network, collaborate, and nucleate new team science initiatives. I would like to support the formation of interest groups to be defined by our early-career members, providing a more constant point-of-contact for young scientists and the AACR. By virtue of these groups being oriented to similar areas of research, I would like to enlist mentors from across the AACR community to engage in individual and group mentoring. By leveraging the AACR community through digital and in-person interactions, we will be able to meet the next generation AACR investigators in the geographically dispersed communities where they are.

The AACR has been the organizing principle behind the collective effort to understand cancer and devise preventative, interception, and curative strategies for more than 100 years. Over the course of my 25-year career, the AACR has substantially extended its translational, clinical, and geographic reach. My hope is to maintain the unity of our purpose under the banner of an expanded vision of team science.

Research Interests

The treatment of melanoma, employing BRAF, MEK, and combined BRAF/MEK inhibition in patients with metastatic melanoma; assessing and identifying mechanisms of de novo and acquired resistance to BRAF inhibitor therapy; clinically evaluating and understanding proximate and downstream consequences of next generation MAP kinase inhibitors, novel metabolism, and epigenetic modifiers to overcome therapeutic resistance.
