Described as one of the strongest field of competitors in several years, San Jose State University will be sending the maximum number of student researchers allowed per campus to the California State University Student Research Competition in April. The finalists include two teams of two students each as well as eight individuals who will compete against hundreds of students from across the system for top honors.

“We had some very strong presentations this year,” said Gilles Muller, associate dean of Research for SJSU’s Office of Research. The finalists made pitches to a panel of faculty judges Feb. 26 and 27 at the Dr. Martin Luther King Jr. Library as part of SJSU’s Student Research Competition.

This year marked the 40th anniversary of SJSU’s campus competition, with individuals and student teams competing from five colleges in five categories. This year, the discipline categories included Biological and Agricultural Sciences; Health, Nutrition and Clinical Sciences; Physical and Mathematical Sciences; Engineering and Computer Science; and Business, Economics and Public Administration.

Richard Bridges, a graduate student in the SJSU College of Health and Human Sciences, is among the students moving onto the CSU-wide competition. He presented his project, titled “Tertiary Treatment of Hepatitis C as Prevention for End Stage Liver Disease: A Qualitative Study Examining the Barriers and Facilitator to Treatment of Chronic HCV Among Current and Former Intravenous Drug Users”. His faculty mentor was Dr. Monica Allen.

Conducting his research among a group of nine black men in San Francisco’s Bayview district, Bridges wanted to investigate reasons for the sharp increase in deaths related to Hep C noted nationally by the Centers for Disease Control and Prevention between 2003 and 2013, and what type of barriers people of color, some of whom contract the disease through intravenous drug use, face in trying to obtain treatment, among other issues.

One barrier that Bridges discovered was a concern by health insurers and providers that drug users could be reinfected after treatment. One of the faculty judges asked Bridges if he found many studies on the subject already available.

“There has been very little research into this disease among this population, and it’s because of the stigma of IV drug use,” he said. “The population in my study does not get the press.”

He added that a new emphasis is being put on the disease by big pharmaceutical companies given its prevalence among baby boomers, those born between 1946 and 1964, most of whom are assumed to have health insurance.

Another team of student researchers who made the cut were Jobelle Peralta and Blake DuPriest, students in the College of Science. Dr. Bree Grillo-Hill served as faculty mentor for the project titled “A New Paradigm for Regulation of Cell Death by Intracellular pH Dynamics in the Fly Eye.”

The pair used cells from the eyes of the insect to assess how the levels of acidity and alkalinity could determine whether those cells would remain healthy or become cancerous. They also examined the causes of cell death in the fly so they could devise strategies to block those causes.

“We were surprised by the results, but that is science,” Peralta said. “You’re always surprised by the results.”

Other finalists in the SJSU competition heading to Fullerton for the competition on April 26 and 27 include:

  • Eric Anderson, Charles W. Davidson College of Engineering, — “Can 3D Printing Compete with Mass Production: A Mechanical Reliability Approach.” Faculty Mentor: Ozgur Keles
  • Sky Eurich and Shivangi Agarwal, Charles W. Davidson College of Engineering — “Takeover Response Times Following Disengagements in Semi-Autonomous Vehicles.” Faculty Mentor: Francesca M. Favaro
  • Avni Gulati, Charles W. Davidson College of Engineering — “Social Recommendation Systems.” Faculty Mentor: Magdalini Eirinaki
  • Sambhav Gupta, Lucas College and Graduate School of Business — “Artificially Intelligent (AI) Tutors in the Classroom: A Needs Assessment Study of Designing Chatbots to Support Student Success.” Faculty Mentor: Yu Chen
  • Vanshika Gupta, College of Science — “Investigating Macromolecular Structures for the Transformation of Greenhouse Gases Into Liquid Fuels.” Faculty Mentor: Madalyn Radlauer
  • Kauionalani Kekuawela, College of Health and Human Sciences — “Differential Cardiovascular Responses to Acute Exercise in Children.” Faculty Mentor: Areum Jensen
  • Sarah Ortega, Charles W. Davidson College of Engineering — “Exploring a Hybrid Design for a Short to Medium Range Transport Aircraft.” Faculty Mentor: Nikos Mourtos
  • Noe Vidales, College of Science — “Clustering Mixed Type Data Sets Using Probability Distance Clustering and Gower’s Metric.” Faculty Mentor: Cristina Tortora

Stellar student researches stellar noise

SJSU physics student Stephanie Striegel is involved in research that could help scientists discover new exoplanets.

Stephanie Striegel is set to graduate this spring with a bachelor’s in physics but she already has her sights set high — beyond this galaxy to be exact. Last summer, Striegel interned at the Carnegie Observatories in Pasadena with Dr. Johanna Teske, where they conducted research on mitigating stellar noise using high cadence radial velocity observations for the purpose of detecting small exoplanets. Exoplanets are planets that orbit a sun other than our sun, according to NASA. Scientists are particularly interested in identifying these bodies beyond our galaxy in their search to find a place that might be habitable.

Striegel’s summer internship was offered through the CAMPARE program, which recruits students from California State University and California community colleges to engage in research, with a goal of increasing underrepresented students in the sciences. She was awarded a $3,000 grant from Sigma Xi Grants-in-Aid of Research program to fund an observing run at Las Campanas Observatory in Chile to collect more data on her stellar noise project with Teske during the school year. According to Sigma Xi, 12 percent of the 810 applicants who applied were approved for funding, and of those approved, only 17 percent were undergraduate students.

While she completes the final courses of her undergraduate career, Striegel is also engaged in an internship at NASA’s Ames Research Center (ARC). She is working with Dr. Tom Greene on reducing laboratory data and performing detector characterization for infrared instruments to enable future studies of habitable exoplanets.

“The classes at SJSU have prepared me for my internships both at Carnegie Observatories and NASA ARC,” she said. “Our physics department has a focus on computational physics, which has been especially useful since a lot of astronomy research requires programming skills.”

Before beginning her internships, Striegel worked with Associate Professor Aaron Romanowsky’s student research team. His research group was focused on ultra-compact dwarf  (UCD) galaxies, which are brighter and more compact than typical dwarf galaxies. Her task included mining the Sloan Digital Sky Survey catalogue for possible candidates by analyzing the characteristics of confirmed UCDs and using SQL queries to do comparisons around galaxies in the local universe. Along with other scientists, Romanowsky’s team hopes to discover how UCDs were formed, specifically if they were part of larger galaxies.

“I’m very grateful for the Physics and Astronomy department at SJSU,” she said. “My peers and the faculty here have been nothing but supportive, and every internship or opportunity I’ve had, I owe to them.”
