SKILLS AND EXPERIENCES
Optical Engineering
- 4 years of hands-on experience conducting multiple electro-optical metrologies and device measurements via spectrometry, reflectometry, ellipsometry, AFM, and IV characterization.
- Designed, developed, and optimized a transparent conductive electrode with PVD coated layers of metals and oxides. Electro-optical properties similar to ITO but at fraction of the cost.
- Designed and characterized Fabry-Perot interference filters based on Al/MgF2/Al with measured optical properties in full agreement with MATLAB simulation results.
- Researched, designed, and fabricated thin film photovoltaic devices incorporating nano- gratings via holographic laser interference lithography, with ease of roll-to-roll processing.
- Operated and maintained hardware and software controlled instruments, including optical servos, AFMs, multi-watt diode and gas lasers, spectrometers, and four-point probe devices.
- Led the electrical team and collaborated with mechanical and software teams during design, testing, and assembly of a prototype robotic prosthetic arm. Subsystems included BJT H- bridge motor driver, resistive force sensor feedback, ADC, and Arduino signal processor.
- 7 years of experience with board-level circuit design and debugging, with usage of digital and analog oscilloscopes, function generator, spectrum analyzer, lock-in amplifier, and OSA,
- Designed and prototyped circuits including linear/digital amplifiers, oscillators and modulators, DC-DC converters, wearable bio-potential sensor, and touch sensitive keyboard.
- Proficient in the usage of CAD programs including PSpice, LTspice, and EAGLE CAD.
- Extensive experience programming in MATLAB, as well as LabVIEW, C, and Arduino.

PROFESSIONAL EXPERIENCES
Applications Engineer - Iridian Spectral Technologies (2016 - 2017)
- Spearheaded new product development from concept to creation:
- Completed specification reviews for incoming request-for-quotes (RFQs), conducted yield estimations, contacted external suppliers for quotes, reviewed and approved process flows. o Collaborated with members of internal departments (sales, planning, deposition, processing) to ensure customer’s specifications are met while maintaining optimal manufacturing efficiency and performance.
- Designed, modelled, and refined filter systems with up to 600 layers of alternating high and low index materials to achieve demanding spectral and mechanical specifications.
- Thorough understanding of optical concepts such as wavelength, bandwidth, AOI, OD, PDL, PMD, CD, GD, Gaussian beam, cone half angle, and their effects on product applications including microscopy, Raman spectroscopy, and CWDM/DWDM/x-skip-y WDM modules.
- Generated white papers on company’s existing products, and held conference calls with customers to discuss new business opportunities and implementations of our products.
- Diagnosed and troubleshot various run-time errors including high deposition layer merit functions due to measurement and/or model errors, developed correction systems, and reinitialized systems that triggered halts.
- Generated data sheets and optical/mechanical assembly drawings for new products, and cataloging these products onto the website.
- Prepared technical presentations on company’s products, including LED light sources, LED driver systems, CCD/CMOS cameras, and spectrometers, and patterned illumination (spatial light modulator) based on digital micromirror device.
- Consulted with customers to provide product sales and technical support, and develop custom implementations of our systems for specific applications ranging from optogenetics and biophotonics to OEM and industrial assemblies.
- Software product management including proposing, implementing, and tracking new software features, based on customer feedback and discussion with team members.
- Trained students and fellow TAs on the operation of lab instruments, including power supplies, digital multi-meters, oscilloscopes, etc.
- Assisted students individually to go over lab instructions, ensured every student understood the lab requirements and correct lab procedures.
- Built, demonstrated, and troubleshot simple electrical circuits (including RLC filters, LED drivers, transimpedance amplifiers, motor drivers) with individual groups of students.
- Lectured, setup, and demonstrated simple experiments including Hooke's law, conservation of energy, kinematics and dynamics of a toy car (conservation of momentum), Young's Modulus of various geometries of materials.
- Graded students’ pre-labs, data measurements, and lab reports; provided feedbacks for the students and the course coordinator.
- Liaised with the course coordinator to track and implement course improvements.
- Rated by students as friendliest and most helpful TA based on feedback evaluation reports.
VOLUNTEER EXPERIENCES
Better Education Donation (BED) Fund Coordinator - Queen's University (2012 - 2013)
- Acted as the primary liaison and relayed communications between the Physics Council and the Engineering Society of Queen’s University.
- Surveyed current laboratory equipment, collected feedback from students, technicians, professors; generated financial reports, consulted with vendors, and purchased new equipment and upgrades.
- Participated in weekly Physics Council meetings, discussed relevant events that occurred during the week and agenda for next week.
- Planned and organized council sponsored events, and relayed information to the undergraduate physic and engineering physics students.
- Directed incoming parents and children to the drop-in center. Chatted with parents (many of which had poor English comprehension skills) and explained program activities.
- Participated in various activities and games with children ranging from toddlers to teenagers, individually and in group settings.
- Served snacks and lunch, cleaned-up after the children, and washed the dishes and utensils.
ACCOMPLISHMENTS
Queen's Space Engineering Team (QSET)
- Worked within a multi-disciplinary team of engineering students (electrical, mechanical, software) in the design, construction, and testing of a robotic lunar rover, which went on to compete in a NASA hosted competition
- Two-time winner of the annual Clark Hall Science Fair Award (2013 and 2016). The awards were given following a brief presentation and demonstration of my design project in front of a panel of judges and student audiences. First award (2013) was for the design and construction of a microwave wireless energy transfer device, and the second award (2016) was for a spark-gap operated Tesla coil.
- See my Personal Portfolio pages for a complete list of personal projects I undertook.
