LiXue Jiang

I obtained my Ph.D. from the Institute of Chemistry, Chinese Academy of Sciences, in 2019. I studied ion-molecule reactions in gas phase using mass spectrometry as well as instrument development. Then, I continued the application and development study of mass spectrometry coupled with superconducting tunnel junction detectors in Carnegie Mellon University.  In November 2021, I joined Dr. Laskin’s group at Purdue University where I am interested in developing an automated system for high-throughput nano-DESI source. My dream was to be a writer when I was a kid.

I received a B.S. in chemistry from the University of Georgia before attending a fellowship position at the Centers for Disease Control and Prevention in Atlanta, where I quantitated biomarkers of tobacco smoke in human blood and serum using GC-MS. I joined the Laskin group in 2019 where I am working on the development of ion soft-landing instrumentation. I have a passion for aviation. I got my pilots license in highschool, but do most of my "flying" on simulation games I play on my custom built gaming PC. Sir Isaac Newton is my favorite scientist.

I received my B. Sc. in pharmaceutical sciences from Misr International University (MIU) in Cairo, Egypt. I then pursued my Master’s Degree from Suez Canal University (SCU) in pharmaceutical analytical chemistry. It was during that time that I received a year-long research internship in the lab of Tsutomu Masujima at the Institute of Physical and Chemical Research, or RIKEN in Osaka Japan, where I investigated the methodology and applications of nano-ESI single cell metabolomics. I joined Dr. Julia Laskin’s group in November 2021 with an interest in in the further advancement of the nano-DESI mass spectrometry imaging system and its future biological applications. My favorite vacation activities are snorkeling and parasailing. Ahmed Zeweil is my favorite scientist.

Mushfeqa Iqfath

I recieved a B.Sc. in Chemistry from University of Dhaka, Bangladesh and then completed my MS in Physical Chemistry in 2020. During my MS thesis, I worked on a project where I explored the area of properties of ionic liquid based microemulsions with a special focus on their surface properties. In 2021, I came to Purdue University as a graduate student. I joined Dr. Julia Laskin's group with an interest to perform multidisciplinary research projects in the field of bio-analytical chemistry. Here my focus lies in nano-DESI MS imaging of biomaterials. I am an ardent reader of fiction, specially Bengali literature. When I am not doing science, either I am cooking or watching mystery thriller movies. Rabindranath Tagore is my favorite writer.

Syeda Nazifa Wali

I received my BS and MS in Chemistry from the University of Dhaka, Bangladesh. There I worked on the synthesis of semiconductor metal core-shell nanoparticles in a microemulsion medium for their potential application as photocatalysts. I joined the Laskin group in October 2021 and am interested in the development of nano-DESI mass spectrometry imaging. I love talking to people, I enjoy reading as a pastime and trying out new recipes, which I think is a rather convenient hobby to have . It is almost beyond my ability to watch a series one episode at a time, so at any given time period, I end up watching either too much or zero tv shows, and nothing in between.

Raquel Cericatto Konzen

I received a B.S. in Chemistry from Universidade Tecnológica Federal do Paraná (UTFPR), Brazil. I got a Master's degree in Environmental Science and Technology (PPGCTA) from the same university. During this time, I worked on the development of multiple adsorbents to remove contaminants from water. After my master's, I worked as a lab technician (chromatography), and as a contractor for a food company, where I developed and validated an HPLC method to detect and quantify sweeteners. I joined Dr. Julia Laskin's group in November 2022 with an interest in working on the development of ion soft-landing instrumentation. I love watching cartoons - favorites at the moment: Rick and Morty, Billy & Mandy, and Clarence. Carl Sagan is my favorite scientist.
