METRIC Graduate Interns

Ying Xi

Ying received her Bachelor of Science in chemistry from Nanjing Normal University, Nanjing, China in 2019 and is currently pursuing her Ph.D. in analytical chemistry under the guidance of Dr. David Muddiman. Her graduate research focuses on infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) mass spectrometry fundamental development and applications. She is excitedly joining the METRIC proteomics team this Fall of 2022.

Russ Kibbe

Russ received his BS degree in chemistry from Wofford College, Spartanburg, SC in 2021. He is currently pursuing a Ph.D. in analytical chemistry at North Carolina State University under the supervision of Dr. David Muddiman. His doctoral research has focused on fundamental work to improve the IR-MALDESI mass spectrometry imaging platform for the investigation of human health and disease. Russ joined the METRIC Mass Spectrometry platform in Fall 2022 performing HRAM analyses.

Grace Scheidemantle

Grace received a B.S. in Biochemistry from Missouri Southern State University and is currently working on her Ph.D. in Molecular and Structural Biochemistry at North Carolina State University in the laboratory of Dr. Xiaojing Liu. Her graduate research focuses on understanding the dynamic metabolic interactions of drugs that target metabolism using novel metabolomics and lipidomics methods. Grace joined the Mass Spectrometry Platform at METRIC in Fall 2021 as an Intern for HRAM analysis. In Fall 2022, she became a Metabolomics Intern for METRIC.

Allyson Mellinger

Allyson received her BS in Chemistry from Wake Forest University in 2018. Her interest in analytical chemistry developed while working under the direction of Dr. Christa Colyer. During her time in the Colyer lab, she was able to pursue diverse research projects in academic, industrial, and international laboratories over the course of two years. It was in the industrial toxicology lab Ameritox that she was first exposed to the power of mass spectrometry (MS), and it was her interest in this field that led her to the NC State University Chemistry program to pursue a graduate degree under the directions of Dr. Michael Bereman and Dr. David Muddiman. Her doctoral research has focused on developing and utilizing novel mass spectrometry techniques to investigate human health and disease, specifically in the fields of proteomics, metabolomics and imaging.

Hellena (Hongxia) Bai

Hellena received her BS degree in chemistry from Tongji University, Shanghai, China in 2018. She joined North Carolina State University later that year to pursue a Ph.D. in analytical chemistry under the guidance of Dr. David Muddiman. Her doctoral research focuses on three-dimensional mass spectrometry (MS) imaging using infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI). She began her proteomics journey when she was an undergraduate researcher and joined the proteomics team at METRIC in Spring 2021. Hellena has 5 years of experience with MS-based workflows in both small molecules and proteins.
