Juan Canoura

Juan Canoura has always been interested in science, but it was his high school chemistry teacher who helped him understand how deeply rooted chemistry is in our lives. 

“I had a very enthusiastic chemistry teacher who would show us how computer technology was linked to the chemistry of silicon, or how biological processes necessary for life are a consequence of the varying structures and connectivity of oxygen, nitrogen, and carbon,” Juan says. 

He became convinced that chemistry is the core science, and this belief motivated him to pursue a degree in chemistry as an undergraduate student. He received his undergraduate degree in chemistry from FIU and is now a now a third-year doctoral student in the Department of Chemistry and Biochemistry. 

Juan’s resolute belief in the power of chemistry remains. “Even now when faced with a challenge in my research endeavors, I know if I can tackle it from a chemical standpoint, everything at the macroscopic level will fall into place,” he says. 

Those research endeavors were recently featured in the Journal of the American Chemical Society. His work focuses on improving the detection of small molecules by using an exonuclease mixture and specific DNA sequences to make the molecules more readily detected.  

“We have taken this complex mixture of compounds with varying structure and properties and simplified them into target-specific DNA molecules which can be more readily detected using traditional DNA detection assays,” says Juan, a McNair Fellow. Practical application of this process could be used to improve screening in situations where samples may be limited, such as medical diagnostics, drug screening, and environmental safety. 

Juan’s decision to join the chemistry doctoral program at FIU grew from his desire to continue working with his mentor, Dr. Yi Xiao, who provided him with a wealth of opportunities as an undergraduate student. His interests closely aligned with her research direction, so he was able to further his career development by becoming involved in various projects, proposals, and papers. Her guidance during his undergraduate research helped him improve his persistence and critical thinking skills. He also honed his experimental skills in her lab, and in instances when the technology he needed wasn’t available onsite, he was able to receive training from collaborators.

“Dr. Xiao always provided me with support to attend scientific conferences as an undergraduate so that I may learn about the cutting-edge research within my field and disseminate my research findings,” Juan says. “By the time I had graduated with my undergraduate degree, I was impressed by the sheer amount of growth I had experienced in Dr. Xiao’s lab. Dr. Xiao has also had my best interest at heart, and I knew that by joining her lab, I would continue to grow and better myself as a person and researcher.”

After completing his doctoral degree, Juan plans to become a professor. He wants to continue his research as an independent investigator and tackle critical issues in medical diagnostics, environmental safety, and law enforcement. He also hopes to become a mentor to future scientists and have the same impact on their lives that Dr. Xiao has had on his.

In addition to his professional goals, Juan is an avid cycler and would like to participate in the Tour de France one day as a nonprofessional.

Chintan Bhatt

Chintan Bhatt, a doctoral student at the Robert Stempel College of Public Health and Social Work, was interviewed live on NPR Atlanta on July 19 for his research paper titled “Medicaid Expansion and Infant Mortality in the United States.”

Published in the American Journal of Public Health (AJPH), Bhatt’s research examines the possible effects of Medicaid expansion on infant mortality rates by comparing infant mortality rate trends in states and territories by whether or not they accepted Medicaid expansion — stratifying by race and Hispanic ethnicity.

You can view Chintan’s interview below, which begins at 27:00 and ends at 36:50.

Using data from the National Vital Statistics System, Bhatt discovered that infant mortality rates declined in both Medicaid expansion and non-Medicaid expansion states between 2010 and 2016. However, the decline in Medicaid expansion states proved to be 50 percent greater than in non-Medicaid expansion states.

Declines and differences in states affected by Medicaid expansion were greatest in African American infants. This drove the overall infant mortality rate difference by Medicaid expansion and reduced the infant mortality rate racial disparity in Medicaid expansion states.

“Publishing and disseminating these findings has been extremely important to me, as the future of medical insurance coverage in the nation is presently under review,” says Bhatt, whose research findings suggest that Medicaid expansion may be an important way to address longstanding disparities in U.S. infant mortality by race.

Millions of Americans were affected by the Patient Protection and Affordable Care Act (ACA), which resulted in changes to health care benefits, coverage and related regulations. Since ACA was implemented in 2014, the uninsured rate decreased, specifically among women aged 18 to 64 years and in the 31 states and Washington, D.C., which accepted Medicaid expansion.

The most frequent users of medical services are pregnant women, mothers and infants, making them potentially the most likely beneficiaries of Medicaid expansion. The Medicaid program has financed coverage for low-income pregnant women for years, covering approximately 45 percent of U.S. births. Medicaid expansion states are required to cover 10 essential health benefits including pregnancy, maternity, pediatric care, chronic disease management, breastfeeding support, contraception, mental health, substance abuse screening and treatment and other behavioral health services.

Bhatt says, because of the dynamic maternal, infant and child health care services required by Medicaid expansion, it may be one of the most important ways in which the ACA may improve maternal and child health outcomes, such as infant mortality.

Bhatt is a medical graduate from India. He obtained his Master of Public Health (MHP) in epidemiology from Stempel College and is a currently a doctoral candidate in the college’s Department of Health Promotion and Disease Prevention.

Ben Wilson and Shelby Servais

Doctoral candidate Shelby Servais and doctoral graduate Ben Wilson have been selected as Science Policy Fellows through the National Academies of Sciences, Engineering, and Medicine’s Gulf Research Program. Funded by the Deepwater Horizon settlement, the fellowship places scientists with offices in Gulf Coast communities so that they can experience the intersection of science and policy  first-hand and learn how science can inform policy and decision-making. Fellows spend one year on the staff of federal, state, local, or non-governmental, natural resource, oil and gas, and public health agencies in the Gulf of Mexico region.

Ben and Shelby’s research interests focus on how saltwater intrusion affects plant and soil environments. Shelby’s dissertation investigated how changing environmental conditions affect soil microbes. In the Florida Everglades, she tested how saltwater intrusion alters how soil microbes process carbon nutrients. Ben’s research has focused on how coastal wetlands respond to a changing climate. He has investigated how rising sea levels and saltwater intrusion will affect plant and soil communities. 

Shelby earned her B.S. in environmental science from Mount Saint Mary’s University and will receive her Ph.D. in biology from FIU in Summer 2018. She conducted the research for her dissertation in the Florida Coastal Everglades Long-Term Ecological Research Network, a network of research programs located at sites that support study on the influence of long-term and large-scale ecological events.  Enthusiastic about science outreach, Shelby served as a Science Communication Fellow at the Frost Museum of Science in Miami while completing her graduate program. Shelby will be hosted by the U.S. Fish and Wildlife Service in Fairhope, Alabama during her Science Policy Fellowship.

Kendra Adams

Kendra Adams is a 5th-year doctoral student in FIU’s Forensic Chemistry program. A native of Burnt Hills, NY, Kendra earned a B.S. in Chemistry with a concentration in Forensic Science from SUNY Albany in 2013. At FIU, Kendra is specializing in Analytical Chemistry.

Kendra, a member of UAlbany’s Division I track and field team during her four years there, became interested in analytical chemistry during her junior year. That year, she took a forensic science class where she had the opportunity to use mass spectrometers to design her own research project.

“After learning about the capabilities of mass spectrometry, I became very interested in pursuing research and joined a research group as an undergraduate,” Kendra said. The work resulting from Kendra’s undergraduate research project was published in a peer-reviewed journal, Drug Testing and Analysis.

Kendra has continued her mass spectrometry work and has published four papers as a graduate student at FIU. Her doctoral work involves using trapped ion mobility spectrometry and mass spectrometry (TIMS-MS) to weigh molecules and experimentally determine their size and shape. This process enables her to measure and identify compounds in complex mixtures.

“Specifically, I have done research looking at various endocrine disruptors, drugs of abuse, and lipids in biological matrices,” Kendra said. TIMS-MS facilitates separating and identifying these types of compounds.

Kendra became interested in FIU because of the forensic track offered in the chemistry doctoral program. “Although I haven’t pursued the traditional forensic route with my research, the analytical work I do can be applied to forensically relevant questions and research,” she said.

After defending her dissertation, Kendra will work as a postdoctoral associate at Duke University, where her research will be focused on Alzheimer’s disease.
