Allison Lim

Materials Chemist


Allison is a materials chemist interested in solving interdisciplinary and human centric problems with soft materials. Originally from the Bay Area, CA, Allison graduated from Harvey Mudd College ('16, Materials Chemistry) and completed her PhD under Dr. Alan Sellinger at Colorado School of Mines ('20, Materials Science).  Allison's graduate work focused on applying organic chemistry and polymer science techniques to plastic scintillators for detection of special nuclear materials (...things like uranium and plutonium). Allison thrives on interdisciplinary projects with creative and collaborative solutions and seeks out opportunities to use organic and polymer chemistry to tailor materials for specific applications.

Outside of lab, you might find Allison playing soccer, hiking, reading about cephalopods, or photosynthesizing somewhere sunny.

Improving Material Properties of Plastic Scintillators

Commercial and synthesized cross-linkers as well as novel synthesized dopants mitigate undesirable plasticizing effects in PSD capable plastic scintillators.

Polysiloxane Scintillators Capable of Pulse Shape Discrimination

Polysiloxane scintillators with low dopant loadings (<5 wt%) perform similar to or better than commercial thermoplastic scintillators.

Photopolymerized Plastic Scintillators Capable of Pulse Shape Discrimination

Plastic scintillators can be fabricated via photopolymerization without sacrificing radiation detection capabilities.
