Dr. Innocent Achaye


Dr. Innocent Achaye is a lecturer in the Department of Chemistry, at Gulu University. He is an expert in mineral processing and has explored to great depths the effect that mineral particles have on the stabilities of froths. He is also very proficient in the design, modeling, and simulations of chemical processes. He is currently involved in supervising graduate research at both Masters and PhD levels. He hopes to utilize the knowledge and experiences gained to help develop the industrial sector of Uganda.
