Applied category theory / computer science research: developing new tools in AlgebraicJulia for compositional and transparent knowledge representation + scientific computing.

Applied category theory with James Fairbanks

San Francisco Bay Area

I apply machine learning to computational chemistry problems and study knowledge/data integration issues in computational science more broadly.

(2020) Applies formal methods towards verification of Android build system code.(2019) Explored applications of feature learning, feature selection, and network pruning / quantization algorithms, in the context of specialized hardware for next-generation ML.

Lausanne Area, Switzerland

I'm investigating techniques to control the surface features of base-metal supported nanoparticle catalysts to mitigate catalyst sintering and poisoning, such that these inexpensive metals can be feasibly used to catalyze liquid-phase biomass conversion reactions.

Hamburg Area, Germany

I wrote and implemented an algorithm to analyze process plant topology by generating fuzzy digraphs, which aid automatic plant disturbance analysis by grouping multiple alarms by root cause to mitigate the problem of alarm flood. In order to do this, I built a library of mathematical functions to relate process disturbances, informed by first principles, in order to determine the relative likelihood of possible fault propagation paths.

Davis, Ca

I collaborated, as the research facility's sole engineer, with biologists to scale up micropropagation operations by designing and constructing novel bioreactor systems. I designed, assembled, and implemented dynamic fluid systems to enable improved monitoring and control of liquid and air exchange with sterile bioreactor network. This work reduced required operator time and risk of contamination by facilitating process automation.

Cambridge, Ma

I tackled many of the elements of process design at this start-up, which pioneered a chemical means for production of cellulosic biofuels. I spearheaded the effort to incorporate particle size distributions into the process model, which improved data resolution on catalyst strength and recovery, and designed the procedure for particle size data collection. I improved a reactor design to address the problem of uneven moisture distribution to maximize yield. To experimentally validate unit operations, I operated a large variety of small pilot scale process equipment and collected data that directly informed company decision-making. Additionally, I led research initiatives into wastewater treatment and corrosion coupon testing, which refined the process model and improving cost-effectiveness of equipment materials selection.

Hanover, Nh

I evaluated gallium (III) catalyzed conversion rates for pyrrolic substrates to produce compounds of interest to the pharmaceutical industry for cancer treatment. I utilized novel organic synthesis techniques to develop a one-step amination process intended to replace the standard multiple step process and eliminate the formation of waste products. This research required daily operation of chromatography columns, NMR, and vacuum pump systems.
