Want to work with David?
David is currently recruiting PhD students for his lab at Purdue, and will also have opportunities for exceptional undergraduate students. Details here.

David is an avid collaborator and eagerly works with faculty as well as postdoc's and graduate students.  Ongoing collaborative opportunities include numerous experimental and modeling journal papers related to membrane nanomaterials, review papers on water treatment membranes, and entrepreneurial work.

Collaborative Capabilities:
David has run experiments with several desalination apparatuses, including for numerous configurations of membrane distillation and reverse osmosis. He also tests membrane properties such as liquid entry pressure, permeate flux, fouling, and is expanding capabilities here. He has done modeling work on: membrane distillation, multieffect distillation, multistage flash, nanofiltration, batch reverse osmosis, and modelling of fouling and crystal nucleation in numerous systems.
