Lucien Lockhart obtained her BA in Chemistry from Agnes Scott College and her M.Ed in Science from Georgia State University. For sixteen years, Lucien has used her love of chemistry and science to create an environment where students become willing to "try" chemistry and physical science despite the challenge level of the classes. She has also been championing Kaplan students to excel in the ACT, PSAT, and SAT pre-college examinations in both classroom environments and as a one-on-one tutor since 2012.
Lucien has recently returned to college to pursue her thesis Masters in Chemistry at GSU and hopes to enter the field of forensics/bioterrorism.
In the almost twenty years that Ed has taught for Kaplan, he has helped well over a thousand students succeed in their academic goals, including standardized tests and exams. Ed holds a Ph.D. in Chemistry and he is well-known for really bad jokes and really good explanations. There is nothing he enjoys more than seeing his students do well.
The older the joke the better - according to Ed.
Megan has been working for Kaplan for over a year, teaching pre-college (SAT & ACT) and MCAT classes. She has a degree in Genomics & Molecular Genetics from Michigan State University Lyman Briggs College, and is now working on a teaching certificate in secondary science. She worked as a TA in general chemistry courses for two years. Her work included attending lectures, leading practice problem/review sessions, and holding office hours.
Biology is Megan’s first love, but chemistry is a close second, and she is excited to help students gain a deeper understanding of it!
With a last name like “Able,” you know you are in good hands for help with Chemistry. Dan holds a BS in Physics & Math from Xavier University and a MS.Ed. in Physics Education from Purdue University. He brings ten years of teaching on both the high school and college level to our ChemHelp students.
Dan enjoys spending time outdoors with his family.

Over the last 13 years, James has been a Kaplan teacher, working with students preparing for medical school and other graduate programs. James has over 15 years’ experience in biotechnology (molecular and microbiology) and academic science labs, so chemistry is second nature to him. His graduate work included the Ph.D. program at the Medical College of Wisconsin and a Master’s degree at Duke University, in which he also obtained a certificate in college teaching. James loves working with students, helping chemistry make sense.
James uses chemistry most days at home in the kitchen. Protein denaturation and precipitation by acidification? Sounds dangerous, but it’s really the basis of making yoghurt and other delicious dishes such as ceviche.
