Tomatoes that beat the heat

When your tomato plants won’t bear fruit during the dog days of summer, a team of Wake Forest researchers led by biology professor Gloria Muday are in the lab trying to find a plant that will thrive. Keyi Huang, a biochemistry and molecular biology major, worked with Muday researching calcium and ROS signaling in tomato pollen under heat stress. Huang’s graduate school interests center around signaling networks in plants and where signal transduction occurs in cells. “The summer URECA research increased my proficiency in operating microscopes and fine-tuned my critical thinking skills. I am more prepared for graduate school studies after working in professor Muday's lab,” said Huang.

Caring for costumes

An accurate database helps keep track of all costumes, props and accessories, ensuring nothing gets lost or misplaced. Junior studio art major Sadie MacDonald worked with theatre professor Mary Wayne-Thomas to create an online database that catalogs and documents the historic garment collection of the theater department. "The research fueled my interest in discovering a future career related to the arts, in curating and learning more about historical aspects of fashion and the construction of garments, and the importance of costume design in theater productions," MacDonald said.

3D models making a difference

Junior engineering major Maxwell Schellhammer and his mentor, engineering professor Tricia Clayton, used photogrammetry, a process of digitizing objects with only pictures, to create high-resolution 3D models for two diverse applications. With Andrew Gurstelle, academic director of Wake Forest's Lam Museum of Anthropology, photogrammetry enabled the digital preservation of 138 unique terracotta artifacts from Niger as a means to repatriation, helping shift research authority to local archaeologists and communities. With Wake Forest University Facilities and Campus Services, drone photogrammetry was implemented to pinpoint erosion hotspots on the banks of Winston-Salem's Silas Creek. "With funding to continue my ongoing research over the summer, not only was I contribute to the Wake Forest community and the city of Winston-Salem, but I was also able to add to the historical preservation of Bura artifacts and ultimately to humanity as a whole in the spirit of Pro Humanitate," Schellhammer said.

Taste and brain processing

Senior Jo Cai, a double major in biology and psychology and her mentor Joost Maier, a translational neuroscience professor in the Wake Forest School of Medicine used flavor perception in rats as a model system to gain fundamental insights into how the brain processes multisensory information. “Working on this neuroscience-related research project enabled me to gain hands-on research experience and to think critically. It helped put me in an ideal position to start applying to PhD programs in my senior year,” Cai said.

3D models for hands-on museum experiences

When it comes to archaeological research, artifact analysis and museum curation, 3D models generated through photogrammetry can be used to allow for hands-on museum experiences and accessibility for visually impaired visitors. Junior anthropology major Annelise Witcher and anthropology professor Andrew Gurstelle created 3D models of Lam Museum objects to create interactive and accessible museum exhibits. Witcher plans to pursue a career in museum curation. “Working with the objects and bringing them to life through photogrammetry has been such a rewarding experience. Not only did I gain a deeper understanding of the objects and their cultural significance, I was able to adjust the models to allow for greater accessibility and interactiveness,” said Witcher.

Chemistry and catalysis

“Engaging in research through the URECA program has been an invaluable part of my undergraduate experience, especially since I plan to pursue a PhD in chemistry,” said junior Leo Liu. His summer research with professor Wendu Ding focused on computationally modeling and simulating the gold catalysis of N-propargyl benzamide in different solvents—a gateway to more advanced catalytic reactions and whose product molecule possesses potential as an anticancer agent, among other biological possibilities. “I have a great appreciation and curiosity for chemistry and its applications across a myriad of fields, whether it be the development of the next life-altering medicine or the minimization of harmful industrial waste in our environment. You can’t possibly find yourself bored with research, because there’s always something new and exciting around the corner. I’m constantly searching for the next ‘UREKA!’ moment.”

Plants and empires

Junior history major T.C. Perez and history professor J’Nese Williams conducted research this summer on a project entitled “Global Empires of Coca: How a Bush Became a Seed for Modern Global Capitalism.” Williams's scholarship includes expertise in the history of science, science and empire, and colonial botany. "Our work aimed to contribute to a more nuanced historical narrative of empire that challenges those that have omitted the intricate relationships between plants and colonial governance," said Perez. The pair spent the summer in the Wake Forest archives analyzing primary sources from Peruvian travel narratives and European encyclopedias to demonstrate the parallel rise of botanical knowledge circulation from Peru and the rise of the Spanish Empire.

Everyday mathematics

Mathematics and computer science double major Alan Pan and Assistant Professor of Mathematics Leandro Lichtenfelz looked at curve shortening flow – a geometric evolution process that characterizes the progressive movement of a curve in the direction of its normal vector. “With guidance from professor Leandro, I had my first hands-on opportunity to see how the theorems we learn in class can be applied to real-life situations. It was the first time I truly felt that math is integrated into every aspect of our lives. From navigation systems to weather forecasting, nearly every technology we rely on today is powered by the capabilities of mathematics,” said Pan.

Glaucoma treatments with fewer side effects

More than 80 million people worldwide have glaucoma. Of these, approximately 11 million are estimated to be bilaterally blind. For her summer research project, senior Samantha Chin worked with Wake Forest Medical School's Dr. Atalie Thompson and health and exercise science professor Gary Miller. The team examined the effect of dietary nitrate in beetroot juice on intraocular pressure as well as the relationship between resting blood pressure and intraocular pressure in search of an alternative treatment for glaucoma with fewer side effects than current medications, such as dry eyes, itching sensation, ocular redness and blurred vision. Chin plans to go to medical school after graduation to study ophthalmology. “This collaboration allowed me to work on team-building skills in a professional setting by seeking guidance and advice while also taking more of a leadership role in a project,” Chin said.

Chemistry and film quality

Chemistry professor Elham Ghadiri’s research focuses on nanomaterials that have applications in biomedical sciences and energy conversion. Sophomore Dany Doughan studied the physical, chemical and optoelectronic qualities of the films produced in the lab using data collected from spectroscopy and photoluminescence tests to characterize the difference between films and to get a better understanding of their qualities and potential. “I am planning to remain on professor Ghadiri's research team for several semesters, and this summer fellowship opportunity provided me with invaluable experience.”
