Post Doc/Research Associate

BS. 2006, PhD, 2012 in Chemistry, Xiamen University, China

Dejun was an exchange PhD student from Professor Shi-Gang Sun's lab at Xiamen University in the Group from October 2009 to April 2012, that was partially supported by a two-year CSC (Chinese Scholar Council) scholarship. He started his current post-doc position in August 2012 working on in situ spectroelectrochemistry (SEIRAS and SERS) and Pt-based electrocatalysts for electrooxidation of small organic molecules and oxygen reduction.

BS. 2006, MS 2009, Sharif University, Tehan, Iran; PhD. 2013, Waseda University, Tokyo, Japan; Post-doc. 2014-2016, Indiana University, Bloomington, IN.

Hamed joined TongLab on September 1st 2016. His research focuses on partial and full electrochemical conversion of methane and on developing in situ IR for studying battery chemistry.

Undergraduate Students

Chemistry major and math minor, Col' 2018.

Florencia graduated from the Thomas Jefferson HS for Science and Technology in Northern Virginia, which is undoubtedly among the most competitive high school in the US. She joined the group in Fall 2015 and started with Yangwei but now with Rongfeng working on synthesizing Ag nanoclusters with different ligands. She intends to go to graduate school after Georgetownl to further her studies in chemistry after the college so she can pursue a career of scientific research and development.

Esther Iyanobor    
Chemistry major and pre-med, Col' 2019

Esther is from Jackson, MS and graduated from Northwest Rankin High School in Flowood, MS in 2015. She joined the group in fall 2016 and has been working with Safia on electrocatalysis of PtNiCu nanoparticles for enthanol oxidation reaction. 

Graduate Students

M.S. in Chemistry, Xiamen University, China, 2012.

Yanyan came from the lab of Dr. Shi-Gang Sun at Xiamen University. She joined the group in Fall 2012 and works on rational design of less expensive bimetallic systems, such as FePt, that can perform better than Pt. She has also been studying sulfur-adsorption enhanced ORR on Pt surface, using both in situ surface enhanced Raman and IR.

Safia Jilani
B.S. in chemistry from Dominican University, River Forest, IL, 2013.

Safia joined the group in Fall 2014, She has won an Espencheid Fellowship for Summer 2015 because she passed her Phase I exams on her first attempt. Her research focuses on developing electrocatalysts that can have a better ability in breaking the C-C bond in ethanol. She has many probing questions, which is good. Moreover, Safia brings a lot of smiles and giggles to the lab.

Rongfeng Zheng
BS (2012) and MS (2015) in chemistry from Jilin University, China.

Rongfeng joined the group in Fall 2015. Before coming to Georgetown, Rongfeng has already co-authored three papers, one of which appeared in Langmuir and entitled "Syntheses and characterization of nearly monodispersed, size-tunable silver nanoparticles over a wide range of 7-200nm by tannic acid reduction". Her research project is on synthesis and characterization of organo-chalcognate stabilized metal nanoparticles.
