Meet Our Speakers
Grace Guo
Senior Technical Specialist Phenomenex
Genevieve Hodson
Senior Application Scientist, Phenomenex
Zeshan Aqeel
Senior Application Scientist, Phenomenex
Grace graduated from the Johns Hopkins University with a Master’s degree in Material Science and Engineering in 2014. In her graduate study, she developed a low-voltage organic phototransistor with an organic small molecule. After her graduation she moved from the east coast to west coast because she loves the all year long sunshine in South California. She spent 3 years in a start-up company as Device Scientist doing single walled carbon nanotube separation and making thin film transistor with them. Most of her experience with Flash system are gained from there. In 2017, she joined Phenomenex as a Technical Specialist supporting globally, especially the Asia-Pacific area. Bilingual in Chinese and English makes it easy for her to communicate with customers in both US and China. At Phenomenex she has more opportunity to have hands-on experience in HPLC, GC and SPE. Discussing the crazy troubleshooting cases with other technical members improves her chromatographic skills every day!
Genevieve graduated from the University of Texas with a BS in Chemistry located in her home town of Austin Texas. She spent 2 years of her undergraduate performing research in an Organic Chemistry Lab synthesizing intermediates. Out of school she spent 4 years as an Analytical Chemist in the QC and R&D Department of Cerilliant (a Sigma Millipore Company). There she worked with many analytical instruments but became an expert at LC by performing purity analysis, customer specific methods, validations, qc testing and stability studies on a wide range of small molecules including pharmaceuticals, pesticides, explosives and illegal substances. From there she moved to Los Angeles California where she worked at Johnson and Johnson and then a small dietary supplement company. After Genevieve spent a year living abroad in Israel raising her first son, she moved back to LA where she got hired as a Technical Specialist at Phenomenex. At Phenomenex she enjoys continuing to learn about chromatography every day through helping customer with all their chromatography needs!
Zeshan Aqeel is part of the Technical Support team at Phenomenex providing problem solving, troubleshooting, and applications support to customers around the world. In this capacity, Zeshan has also assisted in new Phenomenex staff with hands‐on Lab Training and developed and presented many technical seminars as well as demonstrations globally.
Mr. Zeshan has over 15 years of chromatography experience and is an expert in practical HPLC method development. After graduating from California State University Northridge with a degree in Biochemistry, he worked at Amgen and
Baxter Bioscience as an analytical chemist optimizing LC and LC/MS methods.
Joining Phenomenex in 2010 as part of PhenoLogix HPLC/SPE method development team, Zeshan has had a hand in many of the new marketing LC and SPE methods for flagship products such as Kinetex, Strata, Luna Omega and BioZen SEC. Recently, he has been running SEC-MALS and had data presented at 2023 ASMS in Houston.
