I am currently a Postdoctoral Fellow at the University of Pennsylvania, where I obtained my PhD in Condensed Matter Physics in April 2020. Prior to my time at Penn, I graduated from Johns Hopkins University in 2014 with a degree in Materials Science and Engineering with a focus in nanotechnology. I also obtained minors in physics, mathematics, and music theory while taking on a variety of outreach and athletic roles. With varied experience in Python, Matlab, C++, Objective-C, Swift, and HTML, I attempt to come up with interesting ways to combine science, education, and technology in my spare time. In my spare spare time, I also love to travel, play the piano, and spend time with friends and family. Feel free to email me at pmasihd1gmail with any questions, volunteer and coding opportunities, or if you'd just like to say hey :)
I have performed research at a number of institutions around the country such as Stony Brook University, Stanford Research Institute, Johns Hopkins University, and the University of Pennsylvania under the kind mentorship of reknowned scientists. Past projects have covered a variety of topics in materials science, chemical engineering, chemistry, and condensed matter physics. My current research in the Drndic Lab at the University of Pennsylvania is focused on the nanofluidic, optoelectronic, and structural properties of low-dimensional materials using a unique combination of nanofabrication and comprehensive analysis techniques. Specific capabilities include transmission electron microscopy, atomic force microscopy, Raman spectroscopy, photolithography, and (Blender-based) 3D visualizations.

Master Sequencer is an instructional tool that demonstrates the principles of solid-state nanopore DNA sequencing using the well-known Temple Run format. The game involves a player running along a DNA strand, effectively threading it through a nanopore and inducing base-pair-dependent electric current changes, which in turn can be converted into a DNA sequence. Written in Objective-C, Master Sequencer employs the Cocos2D and Google AdMob frameworks. It has been showcased at regional outreach events such as the Philadelphia Science Festival and Philly Materials Day.
The KOH Etch Rate Calculator computes etch rates for silicon (Si) in potassium hydroxide (KOH) solutions for the <100>, <110>, and <111> planes in addition to silicon dioxide (SiO2). Inputs of KOH solution temperature and concentration can be tuned over a wide range in order to obtain the perfect etch rate. Written in Swift, values for the app were graciously provided by Maria Pace's comprehensive web-based KOH Etch Rate Calculator.
I have been involved with the Moelis Access Science outreach program through the University of Pennsylvania's Netter Center since coming to Philadelphia. Access Science has been working to improve STEM education since 1999 by promoting community partnerships between West Philadelphia public schools and University professors, graduates, and undergraduates. From 2014-2015, I performed long-term science fair projects with students from Huey Middle School. In the fall of 2015, I initiated the physics division of Access Science and currently serve as its Curriculum Director. Our program attempts to stimulate hands-on and inquiry-based learning by performing physics lab activities in under-funded West Philadelphia classrooms.
Since the summer of 2016, I have been a visiting scientist at Philadelphia's reknowned Franklin Institute through various partnerships with the University of Pennsylvania. In addition to leading and participating in a number of interdisciplinary workshops for high school students during the academic year, I also perform weekly science experiments with elementary and middle school students in the Institute's annual Summer Camp program.
From 2011-2014, I was a member of Johns Hopkins
Jail Tutorial program, which has been operating at the Baltimore City Detention Center
since 1980. University volunteers in the program provide weekly math, computer,
and language lessons to both male and female inmates in the Center's Juvenile,
Mental Health, Substance Abuse, and General Population facilities. From
2013-2014, I was President of the program and was in charge of coordingating
roughly 40 undergraduate tutors as well as communication between Detention
Center staff, University administration, and Baltimore-based prison reform
During this period, I was also a part of Johns Hopkins' Bootup Baltimore (computer education) and Encore Music (music education) programs in addition to being a teaching assistant at Barclay Elementary School.
Below are a list of science experiments that have been designed over the years for my various teaching positions. Depending on skill level, they are designed for students in Grades 7-11 and cover a wide range of topics such as Newtonian Mechanics, polymer synthesis, and DNA extraction.
