About David Graff

I work on developing methods and tools for computational drug design using machine learning and optimization. I was a synthetic organic chemist in a past life, and I bring that context into my current work on using computational techniques to accelerate drug discovery. Avid distance runner and cyclist- I'll add swimming to the mix when my joints give out. If it goes fast or requires an unreasonable amount of endurance, I'm probably a fan.

    Advisor: Connor Coley (MIT ChemE)- Designing novel algorithms to enable the application of continuous optimization techniques to discrete, non-enumerated spaces (e.g., virtual chemical libraries)- Researching model-free optimization techniques for efficient traversal and search through virtual libraries based on a given property objective (e.g., docking score, ADME properties, etc.)
  • Harvard University
    Graduate Research Assistant
    Harvard University Jan 2020 - May 2023
    Cambridge, Massachusetts, Us
    Advisors: Connor Coley (MIT ChemE), Eugene Shakhnovich (Harvard CCB)- Developed software (MolPAL) to accelerate ultra-large (> 100M) molecular docking screens using Bayesian optimization, machine learning, and cheminformatics- Established Design Space Pruning (DSP), an algorithmic extension to active learning that can reduce overhead costs associated with surrogate ML model inference by 60-80% while retaining optimization performance- Lead developer of Chemprop, a Python package for machine learning using directed-message passing neural networks. Rewrote the entire codebase from the ground up as Chemprop2, increasing the speed by 40% while reducing the footprint by 50%- Refined roughness index to enable quantitative comparison of QSPR surface roughness across multiple representations (ROGI-XD). Utilized ROGI-XD to better understand the performance of unsupervised chemical representations from LLMs, VAEs, and pretrained GNNs, in various QSPR benchmark tasks.- Collaborated with experimentalists to utilize MolPAL in the identification of novel antimicrobial compounds

    Undergraduate Research Assistant in the Knowles Research Group where I worked to develop a novel, photocatalytic method for olefin hydroamination that was published in a high-tier, academic chemistry journal. Further aided in the elaboration of this reaction into an enantioselective variant that was also published in a high-tier chemistry journal.
  • Princeton Tutoring
    Private Tutor
    Princeton Tutoring Nov 2014 - May 2017

  • Harvard Medical School
    Bcmp Summer Scholar
    Harvard Medical School Jun 2016 - Aug 2016
    Boston, Ma, Us
    The BCMP Summer Scholars Program is a summer research program through the Department of Biological Chemistry and Molecular Pharmacology at Harvard Medical School. Students conduct independent research projects under the individual guidance of a faculty mentor and attend weekly seminars where various faculty in the BCMP present on their group's research. During this time, students function as full members of their respective labs, attending lab meetings and other functions, and ultimately conclude with a written manuscript of their research project. This research then culminates with an oral presentation.
