Ask A Scientist

Have an idea for an experiment, but aren't sure how to proceed? Need help interpreting the data you have collected? Looking for advice on scientific research? Ask A Scientist from the Journal of Emerging Investigators offers an opportunity to correspond with a scientist pen pal to answer all of your questions. Simply fill out the form below, and we will match you with a scientist who can help get your experiment off the ground and ready for publication!

You may also be interested in filling out an Experimental Design Worksheet (PDF). While this is not required we recommend spending some time with it, as it will help you design and prepare for your experiment.

Our Volunteers

Sarah Bier

Email: sarahbier(at)

Sarah is a 3rd year Ph.D. student in the Biological and Biomedical Sciences program at Harvard University, where she joined the Mekalanos lab to study how bacterial secretion systems drive interbacterial competition in human hosts and natural environments. Between experiments, Sarah volunteers with a wide variety of science outreach and mentorship programs, advocating for diversity and accessibility in STEM. As COO, she is developing tools to understand JEI's current diversity for staff and authors and building platforms to connect current staff and authors to alumni. She is piloting new programs and collaborations to allow all students to perform science, regardless of their personal circumstances. Outside of science, Sarah enjoys costume design, sculpting, and playing her cello.

Carlos Díaz García

Email: cdiazgarcia(at)

Carlos is a scientist with over 15 years of experience studying the physiology of excitable tissues, with a particular emphasis on how the management of the cellular metabolic workload impacts health and disease. A science enthusiast since a very young age, he was fortunate to have family, teachers, and friends who fostered his interest in nature. Fascinated by the many homeostatic feats that a living organism perform, he decided to become a physiologist while in High School. He did his undergraduate studies in Biochemistry, as well as his Master studies in Animal Physiology, at the University of La Habana, Cuba, receiving formal training in electrophysiology. He then received a PhD in Biological Sciences from the National Autonomous University of Mexico, where he focused on the regulation of insulin secretion and glucose homeostasis. As a postdoctoral researcher at Harvard Medical School, he has studied the changes in energy demand and supply in the stimulated brain, using genetically encoded fluorescent biosensors in combination with 2-photon fluorescence lifetime microscopy. During his academic career, he has also taken on several teaching and mentoring responsibilities. He is a motivated person who enjoys creative challenges and collaborative work, and strongly believes in science as a driving force for progress and wellbeing.

Michael Kelbermann

Email: mkelberman(at)

Michael is a graduate student studying Neuroscience at Emory University in Dr. David Weinshenker’s lab. His research focuses of the impact of Alzheimer’s disease (AD) pathology on a small brain structure called the locus coeruleus (LC). AD is the most prevalent neurodegenerative disorder and a leading cause of death, with incidences likely to rise alongside an aging population. AD is characterized by aggregates of extracellular β-amyloid and intracellular tau neurofibrillary tangles. The LC is the brain’s primary noradrenergic nucleus and is known to degenerate in various neurodegenerative disorders. Interestingly, the locus coeruleus is prone to hyperphosphorylated tau aggregation in AD, often decades prior to the onset of cognitive deficits. The goal of his research is to understand the effects of hyperphosphorylated tau on LC function using a combination of approaches including electrophysiology, optogenetics, and functional magnetic resonance imaging. When not in the lab Michael enjoys hiking around Atlanta, running, and watching/coaching local youth soccer teams.

Doaa Megahed (aka Douaa Mugahid)

Email: dmugahid(at)

Doaa has been an Editor at Nature Communications since September 2020, where she handles Computational and Systems Biology papers. Prior to that she was a post-doc in the department of Systems Biology, where she used a variety of methods to understand the role of a protein called YAP as a regulator of cell-cell communication in the liver and in cultured cells. As a graduate student at Heidelberg University and the MDC-Berlin, Germany she studied how hibernating bears avoid the loss of muscle mass. She continues to serve the scientific community by advocating for papers that advance human knowledge, democratize scientific research, and improve reproducibility in science. She enjoys teaching and mentoring, which is why -besides volunteering with JEI- she is also COO of Maqal 3elmy, an initiative that makes science Accessible to the Arab world. In her spare time, she enjoys reading, traveling, spinning, running, crafting and upholstering old furniture.

Ask-A-Scientist office hours are now available for online counseling sessions

We’re excited to announce a new block of Ask-A-Scientist office hours! Saturday, October 23rd, 2021 at 10-12 am and 8-9 pm EST.

This means that students can speak to a JEI scientist directly through video call to ask questions about anything from experimental design to data analysis, figure generation/organization, scientific writing, and publication with JEI.

Where to sign up? Students interested in signing up for a 30-minute session can visit our Google Calendar here.

How to claim a slot?
