Research Higlights:

Assistant Research technologist, Digital Design and Manufacturing Lab, OSU Feb 2016 – Present

Honda Riv-Tech Project: Multi material contacts, Connecting composites and metals using adhesives and nails

  • Developing an automated system to help designers design a multi material contacts
  • Creating a respond surface, multi attribute function with correction factors, to find a solution for Riv-Tech contacts

Assistant Research technologist, Design Automation Lab, ASU July 2015 – Present

IAMFix project: Adaptive fixturing for machining of high value large casting and fabricated assemblies

  • Using scanning technologies to simulate geometrical features using the Normative Featuring fitting algorithms
  • Developing a fixture library, for a fully automatic system that calculate the required adjustments on the fixtures
  • Creating a digital thread, using PMI info, CAD model annotations, and standard .sat format for transforming geometry

Graduate Research Associate, Design Automation Lab, ASU June 2012 – July 2015

IFAB - AVM project: Developed CAD software to help designers assign correct GD&T schema (Design, 3-D CAD, Automation)

  • Analyzed complex mechanical assemblies (e.g. heavy vehicles drive train) to develop GD&T scheme for assimilability
  • Developed diverse algorithm (Pseudo codes) for an Auto-Tolerancing system and implemented them in an object oriented C++ code; focused on loop detection, tolerance allocation & analysis
  • Designed 3-D CAD (Part and Assembly) test cases; using NX, SolidWorks, Pro-E
  • Given presentations, preparing reports, technical documents, etc; using MS offices (Word, Excel, Power point, Visio)
  • Involved in planning and managing the project as well as working with cross functional teams

MURI project: Health Monitoring of composite & aluminum structures (eg. airplane, bridge) using Lamb-Wave stimulation

  • Performed fatigue tests, with composite and aluminum parts in different temperatures and collected data from piezoelectrics simulated by a National Instruments Data Acquisition (DAQ) system programmed by LabVIEW
  • Analyzed experimental data with MATLAB codes: Noise cancelation, Mode derivation, etc.

MSc. Thesis: Modeling manufacturing errors (creating m-maps) to compare with design tolerances (t-maps)

  • Proposed a new method to model manufacturing process plans for evaluation; consistent with design tolerance evaluation
  • Developed algorithms (C++ codes) to predict accumulation of error through multiple stages of manufacturing Graduate Research Assistant, Adaptive Intelligent Materials & Systems Center, ASU Mar 2013 - Aug 2013

Undergraduate Research Assistant, Center of Excellence in Design, Robotics & Automation, Sharif 2009 – 2011 BSc

Thesis: Vibration of DNA Strands in Healthy and Damaged Cells”

  • Suggested a new method to distinguish healthy cells from unhealthy ones (mutated, cancered cells) by comparing their vibration modes (physical/mechanical properties) reflected in their Raman-Spectroscopy
  • Simulated molecular dynamic to analyzed and extract the vibrational behavior of DNAs
