Henry Lujan Jr., B.S.

Third-Year Ph.D. Candidate

Expected Graduation Date: May 2020



Henry is a native Texan and second-year graduate student in the Environmental Sciences PhD program at Baylor University. After receiving his B.S. in Biochemistry in 2016, he began his role as Graduate Researcher for The Sayes Group. His current projects include gathering information on prevalent nano-therapeutics and the compounds that are commonly used in these nano-therapeutics to treat lung cancer. He is elucidating the potential health risks associated with the recommended doses of each nano-therapeutic along its life-cycle, and analyzing the immune response (i.e. cytokine upregulation or downregulation) and their effect on the JAK-STAT pathway using in vitro model systems. In addition to his work with nano-pharmaceuticals and how they affect lung cells, Henry is working on projects that involve microscopy (transmission electron microscopy, scanning electron microscopy, fluorescence microscopy, bright field/dark-field microscopy), ELISA assays, and viability and growth assays, and liposome synthesis.

Henry’s specialties include, but are not limited to, cell culture, aseptic technique, particle characterization techniques (e.g. zeta potential, dynamic light scattering), and gene characterization and protein expression in lung cells.

The fields of science that interest him the most are nanotoxicology, pulmonary toxicology, cancer biology, and public health. He plans to continue his research in mechanistic toxicology and study toxicological phenomena at the cellular level, as well as report on the outcomes of unexpected exposures to the environment from used nanotherapeutics. Henry is expected to graduate in 2020 and hopes to start a post-doc or fellowship to obtain more experience before his transition into the workforce. Henry hopes to work for the government through the CDC, EPA, or a private organization.
