Hello and welcome
Joshua Sharpes

Chemical process engineer. This is where I keep the projects I've written up, the books that have shaped how I think, and a few of the things I do outside of work.

Projects
Independent write-ups

Reports and models I've put together on my own time, spanning process engineering, energy, and a bit of applied math.

Capstone Projects & Coursework Certifications

Undergraduate capstone design reports, lab research, and professional-development certificates from CU Boulder — the source material behind a lot of the engineering habits I still use.

Capstone & Research Projects
Epichlorohydrin Production — A Process Designed with Dow Chemical
Senior capstone: glycerol-to-epichlorohydrin process design (100,000 metric tons/yr), developed with Dow Chemical liaison Dr. Bruce Hook. Reactor kinetics in MATLAB, a reactive distillation column, ternary-azeotrope separation in Aspen Plus, and a full capital/operating cost study.

Colorado High School Football

Footage from my high school state championship run, alongside a side project: ranking the greatest Colorado high school football seasons since 2004, adjusted for school size and private-school recruiting reach.

P Private school. Nat. Rank = MaxPreps national rank among ~14,500 U.S. teams. Highlighted: 2018 Loveland — the largest margin over its own class of any Colorado season (21 rating points), with 4,704 rushing yards and 72 rushing TDs on a run-first offense.

Method. 4,179 rated 11-man team-seasons (2004–2025) from MaxPreps final ratings, matched to CHSAA enrollment. Score blends performance above what a school's enrollment predicts (45%; private enrollment counted at 2.5×), national standing (25%), margin over the next-best team in the same class (15%), and record (15%), with shortened seasons discounted. 8- and 6-man programs aren't rated by MaxPreps and aren't included.
