Lab Members

Simon W Davis, Ph.D. (Principal Investigator) is an Assistant Professor in the Department of Neurology at Duke University School of Medicine. He completed his PhD at Duke with Roberto Cabeza, where he was a student in the Department of Psychology & Neuroscience. He then trained at the Centre for Speech, Language and the Brain in Cambridge University under Lolly Tyler. Simon is a cognitive neuroscientist with experience in behavioural modelling, psychological task design, neuroanatomy, neuroimaging, and the global and local changes in brain physiology and anatomy associated with aging.

Simon’s Top 7 bands are The Fall, The Fiery Furnaces, Pulp, Guns N Roses, Xiu Xiu, Albert King, and Lambchop.





Mariam Hovhannisyan is Research Technician in the Electric Dinosaur lab. She graduated from UCLA in 2017 with a B.S. in Cognitive Science. Mariam is generally interested in using neuroimaging tools to better understand the aging brain. Her favorite book at the moment is Flowers for Algernon. 




Lifu Deng is a graduate student in the CNAP program. He graduated from Shanghai Jiao Tong University with B.S. in Biomedical Engineering & Applied Mathematics, and M.S. in Biomedical Engineering. Lifu is interested in the dynamics of functional networks in the brain, and how it is influenced by structural connectivity and stimulation. Lifu enjoys outdoor activities and playing music. He’s an amateur in botanics who used to own a collection of bizarre-looking cacti, succulents, and orchids before coming to Duke.







Olga Lucia Gamboa Arana is a physicist with a Ph.D. in Basic and Clinical Neurology.  She is deeply interested in understanding memory, forgetting processes linked to emotion and how these affect well-being. She is also interested in the development of non-invasive transcranial stimulation protocols that in combination with neuroimaging techniques such as fMRI (concurrent TMS-fMRI) and electroencephalography (concurrent TMS – EEG) will allow the assessment of their efficacy and reliability modulating and enhancing cognition. At Duke, she collaborates with Prof. Simon Davis working on an EEG – TMS project aiming to asses, modulate, and enhance brain function in MCI patients.







Lab Alumni

Devi Lakhlani was an undergraduate research student for the Electric Dinosaur lab. She graduated with a major in neuroscience and a minor in global health. In her free time, Devi enjoys dancing on Duke’s classical Indian dance team, Duke Lasya, and volunteering with Duke Helping Hands for Alzheimer’s and other Neurological Disorders (DukeHAND).

Courtney Crowell was a Research Associate in the lab. She graduated from the University of Rochester in 2016 with a B.S. in Brain & Cognitive Sciences/B.A. in Psychology. Courtney focused mainly on fMRI analysis in the lab, and she is interested in research linking brain and behavior in the context of memory and aging. Her favorite documentary is The Barkley Marathons.






Daisy Banta was a Research Technician for the Electric Dino Lab. Originally from Richmond, VA, she braved four frigid New England winters to graduate from Williams College with a degree in Biology and Neuroscience—though she also enjoyed taking classes in Spanish lit, religion, and philosophy. She loves many forms of movement, from rock climbing to dancing to hiking, and can appreciate a good laugh at a standup comedy show. Daisy is excited to spend the coming months learning as much as possible in the lab before heading to Brazil next year, where she’ll be working on her samba steps and language skills. Tudo bem!







Amanda Szymanski was a Research Technician for the Electric Dinosaur. She graduated from High Point University in 2015 with a B.S. in Psychology. She now works at CliniPace, a leader in clinical trials organization. A lover of art, music, and nature, when she isn’t busy creating scripts and analyzing brain imaging data, she can be found painting, hiking, or at the dog park. Bonus: Fable the Fabulous


Eduardo Salgado was an undergraduate student double majoring in Neuroscience and Psychology. With his lab experiences, he hope to pursue a PhD in Cognitive Neuroscience or Clinical Psychology, with the goal of developing research projects that can help directly or indirectly inform interventions for Major Depressive Disorder. When not in lab, he enjoys gaming, checking out cool places to eat in Durham, and sleeping, basically being a bum.






Lena Patel was an Undergraduate Research Assistant for the Electric Dinosaur. She graduated in Spring 2018 with a B.A. in Biology, minor in Neuroscience, and certificate in Markets and Management Studies. Post-graduation, she will be going to New York to do Healthcare Investment Banking with the hopes of bringing together her passions for the life sciences and business. In lab, she assists with histological data collection, but she can also be found in Wilson Gym teaching her H.I.I.T. class, camping out for Duke Basketball games, or spurring conversations of reform as President of the Duke Healthcare Policy Forum.
