About Dr. Bwalya Malama
Dr. Bwalya Malama holds a PhD in Hydrology, an MS in Geological Engineering, and a BS in Mining Engineering from the University of Arizona. Before joining Cal Poly, he was a senior member of technical staff at Sandia National Laboratories in New Mexico where he investigated groundwater flow and contaminant transport related to geologic disposal of nuclear waste. He also conducted research in innovative methods for characterizing near-surface fluid flow and solute transport systems. Prior to his work at Sandia, he held an Assistant Professor position in Geological Engineering at Montana Tech and a research position at Boise State University. Dr. Malama's research interests are in quantitative (analytical and numerical) modeling of groundwater flow and transport of contaminants in the subsurface, lab- and field-scale investigation of innovative physics based methods for characterizing flow in the near-surface and very low permeability environments, and development of empirical models for soil moisture.

Dr. Malama is a bright, devoted, and good-spirited professor. He made me excited to go to this class everyday even though it was in the morning. He was great at presenting the material clearly and was very welcome to students' questions and concerns.
Dr. Malama makes ERSC more fun than it already is! He makes a genuine effort to get to know each student by name and answer every question in great detail. He tries to explain things in multiple ways and repeats them to ensure everyone knows the material and is not lost. He also is super funny and wears awesome hats. The labs are very helpful because they really capture the "learn by doing" aspect of this course.
Dr. Malama is an amazing instructor. He explains everything very well and organizes the lectures in a way that is easily understandable and perfect to take notes from.
Professor Malama is very knowledgeable and has lots of experience in this subject. He is very open for office hours, understandable, and always willing to help.
Dr. Malama is the most fair teacher I have had at Cal Poly. Unlike most professors that I have encountered, Dr. Malama actually respects his students and is willing to give them the benefit of the doubt.
