Engineering Management and Systems Engineering Faculty Research & Creative Works

Undergraduate computer science programs worldwide struggle to attract and retain underrepresented students for many reasons. Culture, stereotype threats, uneven gender and racial representations, lack of role models, and uncertain career prospects for minority groups are among the many reasons behind this situation. Many computer science programs are trying to change course through strategies to foster equity, diversity, and inclusion (EDI), aimed at improving outreach, recruitment, admissions, and retention of underrepresented students. EDI approaches may also include modifications to the undergraduate computer science curriculum. However, if not properly planned, these modifications risk amplifying existing stereotypes rather than producing positive change [38]. …

Abdominal aortic aneurysms (AAA) are a life-threatening cardiovascular disease for which there is a lack of effective therapy preventing aortic rupture. During AAA formation, pathological vascular remodeling is driven by vascular smooth muscle cell (VSMC) dysfunction and apoptosis, for which the mechanisms regulating loss of VSMCs within the aortic wall remain poorly defined. Using single-cell RNA-Seq of human AAA tissues, we identified increased activation of the endoplasmic reticulum stress response pathway, PERK/eIF2α/ATF4, in aortic VSMCs resulting in upregulation of an apoptotic cellular response. Mechanistically, we reported that aberrant TNF-α activity within the aortic wall induces VSMC ATF4 activation through the …

Faculty, Staff and Student Publications

CD73 is ubiquitously expressed and regulates critical functions across multiple organ systems. The sequential actions of CD39 and CD73 accomplish the conversion of adenosine triphosphate to adenosine and shift the adenosine triphosphate-driven proinflammatory immune cell milieu toward an anti-inflammatory state. This immunological switch is a major mechanism by which regulatory T (Treg) cells control inflammation. Foxp3 engages in Treg development and function. Foxp3 mutations result in the scurfy (SF) mouse phenotype and a rapidly lethal lymphoproliferative syndrome. We generated double knockout (KO) mouse (CD73KOSF) by breeding heterozygous Foxp3sf/J females to CD73KO male mice to remove host CD73. We initially aimed …

School of Biological and Marine Sciences

Environmental drivers such as salinity can impact the timing and duration of developmental events in aquatic early life stages of crustaceans, including terrestrial crabs of the family Gecarcinidae. Low salinity delays larval development in land crabs, but nothing is known about its influence on the crucial late-stage encapsulated embryonic or immediate post-hatch development. Therefore, we exposed fertilised late-stage embryos of the Christmas Island red crab (Gecarcoidea natalis) to differing salinities (100%, 75%, 50% or 25% sea water) for 24 h during their spawning period and measured some key developmental and physiological traits. We found no effect of salinity on time …

Student Scholarship

Objective. High-density nerve cuffs have been successfully utilized to restore somatosensation in individuals with lower-limb loss by interfacing directly with the peripheral nervous system. Elicited sensations via these devices have improved various functional outcomes, including standing balance, walking symmetry, and navigating complex terrains. Deploying neural interfaces in the lower limbs of individuals with limb loss presents unique challenges, particularly due to repetitive muscle contractions and the natural range of motion in the knee and hip joints for transtibial and transfemoral amputees, respectively. This study characterizes the long-term performance of these peripheral nerve interfaces, which is crucial for informing design modifications …

Synthesizing Photoprotective Melanin Nanoparticles With A Zinc-Doped Bismuth Oxide Coating To Withstand Uv Radiation, Stefani Capasso Villanueva, Samantha Marie Goldfuss

Student Research Symposium (SRS)

Ionizing radiation is a factor that is linked to increasing the chances of developing melanoma; specifically ultraviolet (UV) radiation, which is produced by the sun. Luckily for us on Earth, there are two natural sources that can protect us from UV, the atmosphere and a polymer produced by our cells called melanin. Both of these sources are able to absorb radiation, shielding our skin from it. However, most UV radiation is absorbed by the atmosphere, and missions done in Low Earth Orbit (LEO) do not benefit from the atmosphere's UV absorbing properties. The aim of this project is to create …
