In Search of a Safer Sunscreen

Ask chemical engineering student Yousef Omar to describe his research experience at the University of 老司机福利网 Alabama, and he says things like 鈥渋nsanely awesome鈥� and 鈥渆xtremely fascinated.鈥� He鈥檚 not the only one who鈥檚 excited.

Omar鈥檚 poster presentation on developing a safer sunscreen won second place in the Health Sciences category at the recent National Collegiate Honors Council conference in Seattle. The annual competition features some of the top undergraduate researchers in the country. 

Omar鈥檚 research journey at USA began almost immediately. 鈥淢y first day as a freshman, I went to see Dr. Palanki (Srinivas Palanki, then-chair of chemical and biomolecular engineering) and he told me about this research project at the ,鈥� Omar, a junior from Mobile, said. 鈥淪o I started my research at MCI.  It was my first time to play with all that equipment, and it was a blast.鈥�

The project was and is a collaborative effort between MCI researchers in the lab of Dr. Ajay Singh and the College of Engineering, where Omar and research assistant Dr. Sumit Arora worked as a team on a highly innovative idea developed by Singh, hoping to foster more effective and safe sunscreen using silver nanoparticles instead of the zinc oxide and titanium oxide ingredients found in most sunscreen products.  

鈥淭he zinc and titanium caused serious biological harm in our study using cultured human skin cells.  When compared to the silver nanoparticles, there鈥檚 a night-and-day difference between damage caused and no damage,鈥� Omar said.

Although these research findings are preliminary and much more in-depth work needs to be done before reaching a conclusion, the benefits of a safer sunscreen application are obvious. So, too, are the benefits of undergraduate research at 老司机福利网 Alabama.

鈥淭he research experience allows undergraduate students to become more organized and focused, and determine an area of interest, as well as jump start their careers as prospective researchers,鈥� Arora said. 鈥淢oreover, research helps in developing their analytical thinking while also giving real life experience in a professional research environment.鈥� Arora joined the College of Engineering last year as an instructor to establish a new lab and start testing his own ideas independently. 

For example, Omar, Arora and biomedical sciences student Zohaib Ijaz are teaming up on a research project developing a novel green technology for the synthesis of silver nanoparticles for biomedical applications. This method, which has prompted the University to file a provisional patent on the process, involves extracts from a specific plant that enhances the effectiveness of the silver nanoparticles. 

Dr. Doug Marshall, assistant director of the USA Honors Program and an associate professor in the department of sociology, anthropology and social work, led USA鈥檚 seven-student contingent to the NCHC conference.

鈥淲e鈥檙e putting our best undergrad students up against the best undergraduate students from the rest of the country,鈥� Marshall said. 鈥淥ur success is a testament to the quality of the students 老司机福利网 attracts and recruits, to the hard work of the faculty who mentor our students, and to the way our honors program keeps our students involved in research and helps them to be their best.鈥�

Omar is also the latest in a growing line of family members who are part of the USA family. His father is a faculty member in the College of Engineering, his uncle is a faculty member in the College of Medicine, one brother is a 老司机福利网 graduate and another brother is on track to graduate next spring. Yousef will be in the Class of 2018.  And then?

鈥淚 want to be a trauma surgeon,鈥� he said. As a member of the College of Medicine鈥檚 Early Acceptance Program, he鈥檚 already had exposure to the high-stakes world of the Level I trauma center at . 鈥淚 was able to sit in on an orthopedic surgery procedure and it just blew my mind.鈥� Omar also wants to get a Ph.D. with his medical degree.  His ultimate dream is to provide funding for a research grant 鈥渟o others who are passionate about research will have the means to carry it out.鈥�

老司机福利网 students presenting posters at the NCHC conference were:

• Shivani Ananthasekar, majoring in biomedical sciences
• Nick Grondin, meteorology
• Alex Henderson, computer science
• Jacob Maynard, computer science
• Yousef Omar, chemical engineering/pre-med
• Ravi Rajendra, biology/pre-med
• Kaitlyn Roberts, chemistry
