Graduate Students:

Akram Ashames |

I am originally from Tripoli, Libya where I received a bachelor's degree in Pharmaceutical Sciences from the School of Pharmacy at Tripoli University. After I worked as a TA for several years at the same school, I went to France to finish my Master's degree in Pharmaceutical Industry Management at Burgundy School of Management . I was then appointed the Director of General Administration of Drug Control. I came to CSM to pursue my doctoral studies with Dr. Williams's group on biological nanovesicles using field-flow fractionation (FFF). My research area focuses on developing new separation approaches for exosomes (30-120 nm) using FFF to produce uniform exosome subpopulations and to characterize them in terms of size, density, lipid composition, and exosome protein biomarkers using different techniques. I spend most of my free time with my family.

Carmen Bria |

I am a Colorado native and grew up in the Denver area, but I spent plenty of time backpacking and skiing in the mountains. I moved to Washington state for college where I earned a Bachelors degree in chemistry from the University of Puget Sound. My research focuses on the use of field-flow fractionation and light scattering to characterize protein aggregates and protein aggregation kinetics. I’m also working on developing improved membrane surfaces for flow field-flow fractionation. When I’m not in the lab I like to do all of the Colorado regular activities, hiking, biking, climbing, camping, and snowboarding. I also love to go see music around Denver and I play guitar in band that plays around the Denver area and Colorado.

Charles (Charlie) Ponyik |

I am originally from an eastern suburb of Cleveland, and completed my undergraduate education at John Carroll University where I received a BS in Comprehensive Chemistry. After working for the Sherwin-Williams Company as a raw materials chemist and also as a polymer applications chemist, I came to Colorado to begin research in Field-Flow Fractionation. My interests here are in the use of separations methods and light scattering to characterize novel polymers for their shape and chemical composition. When I'm not in the lab I love to travel, play new board games, and engage in the fiber arts.

William (Billy) Smith |

Born and raised in Jackson, Wyoming I grew up spending most of my time outdoors hunting, fishing, and skiing with my family. In 2012 I received my B.S. in Chemistry from The Evergreen State College in Olympia, WA. Before coming to Mines I worked as an Engineering Technician assembling and testing prototype designs for Transmission Electron Microscope (TEM) sample holders. While studying various forms of spectroscopy I gained an appreciation and awareness for materials science and how the characteristics of each individual components affect an instruments performance. I hope to eventually work in the field of scientific instrument design. My initial research will focus on the use of Thermal FFF in combination with Multi-Turn channel configurations to increase the throughput and efficiency of separating complex mixtures of polymers. Future research will include development of novel channel configurations and options for on-channel detection. When I’m not studying I enjoy reading a good book, cooking delicious food, making music, and painting. 


Patrick Skelly |

Originally from Albuquerque, New Mexico, I am an undergraduate student here pursuing a B.S. in Chemistry. My research involves semi-preparative asymmetrical flow field-flow fractionation. In my free time I enjoy hiking, reading, drawing, and playing music.
