Register for December Webinars
December brings a trio of HPLC fundamentals topics.
Sign up for all three to refresh your LC fundamentals, receive a certificate of completion, and a free method consultation with one of our technical expert!

If you can’t make it at that time, register anyway and we’ll send you an on-demand recording of the webinar a few days after the event.

We look forward to seeing you then!

To register for free, simply complete the registration form.

Dr. Aidan Harrison is a Field Application Specialist based in Phenomenex U.K. He joined Phenomenex in 2015 as a Technical Sales Consultant, specialising in analytical HPLC and UHPLC, bulk and preparative HPLC and SPE technologies. His current role takes him to customer sites in the UK and Ireland to assist with development of new methods, method transfer and training using HPLC, UHPLC and sample preparation technologies.

Dr. Harrison received his Bachelor of Science degree in Chemistry from Massey University and PhD in Organic Chemistry from University of Canterbury in New Zealand. Both his graduate and post-doc research primarily focused on medicinal and biochemistry, working in drug discovery with experience in organic synthetic chemistry, NMR, analytical HPLC and UHPLC including chiral method development, protein purification and enzymology.
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! 
Rajesh Babu more than 11 years of chromatography experience and is an expert in practical HPLC/UHPLC/LC-MS/GC-MS method development and troubleshooting. Before joining Phenomenex, Dr. Rajesh worked as a Faculty member at Sri Sathya Sai Institute of Higher Learning, Deemed University. He was instrumental in establishing a state-of-the-art mass-spec core facility consisting of GC, HPLC, GC-MS, LC-MS/MS, and HRMS systems. His research work was in the area of clinical metabolomics.
