We wrote a paper describing some electrostatic computations using finite elmenent codes Dr. Xie developed earlier, which was published in the Journal of Computational Chemistry. –> I worked with Dr. Xie to develop “nonlocal” extensions of the traditional PB theory. We published a paper in the Journal of Computational and Applied Mathematics describing a nonlocal PB model for biomolecules in ionic solutions that include ion size effects. In my dissertation, I developed a nonlocal PB model for ion channels, such as VDAC. https://liamjemison.com/projects/poisson-boltzmann/ https://liamjemison.com/about/ Sun, 12 Apr 2026 15:59:45 -0500 ## Education PhD Mathematics.

Portland State University (PSU), 2016 – 2020. ## Positions # Research Positions Graduate Research Assistant UWM, 2022 - 2024 for National Science Foundation grant to advance ion channel and mitochondria computational models. https://liamjemison.com/about/ https://liamjemison.com/projects/sporophyte-detection/ Sun, 12 Apr 2026 15:49:53 -0500 Working with biologists in the Alberto lab at UW Milwaukee, I created a new dataset of over 1300 microscope images of Giant Kelp and Nereocystis sporophytes with hand labelled bounding boxes around sporophytes and eggs. Using this data, I trained object detection machine learning models to identify sporophytes automatically. I contributed a blog post about this project to SIAM news, and I gave a contributed presentation about the topic at the SIAM MPE22 conference in the summer of 2022. I have also created a hugging face space to demonstrate the network we trained. https://liamjemison.com/projects/sporophyte-detection/ https://liamjemison.com/projects/dc-functions/ Wed, 17 Jun 2020 16:35:15 -0500 As an undergraduate at Portland State University I wrote an honors thesis about DC (difference- or perhaps delta-) convex functions under Dr. Mau Nam Nguyen. DC functions are a superset of convex functions – any function expressible as the difference of two convex functions is a DC function – and are of interest as the subject of efficient optimization algorithms. https://liamjemison.com/projects/dc-functions/
