Enthusiastic chemical engineer, eager to work in areas pertinent to applied surface chemistry, polymer processing and characterization.


North Carolina State University, Raleigh, NC

MSc. Sustainable Biomaterials & Engineering 2016-present University of Toledo, Toledo, Ohio

MSc. Chemical Engineering 2014-2016

University of Tehran, Tehran, Iran

BSc. Chemical Engineering 2008-2012


Graduate Research Assistant Jan 2016-Present

North Carolina State University, Department of Sustainable Biomaterials & Engineering Leading and supervising experiences

• Supervised undergraduate/graduate students to work with industrial 3D printer, twin-screw extruder, injection molding and hot-press instrument.

• Leading the project; “synthesis of the bio-based composite of Plastic(PLA)/lignin copolymer for automotive industry”

Related experiences to polymer manufacturing/modification industrial processes

• Working on a surface modification of cellulose fibers, technical lignin and polylactic acid (PLA) via O2 plasma to improve coating/finishing process with polydimethylsiloxane (PDMS). The study focused on the interaction between oxygen-plasma and low surface energy polymers to maximize the coating material adsorption.

• Design & Fabricating sustainable nanocomposite of cellulose nanocrystal (CNC)-ABS and lignin-PLA via solidworks and 3D printer/injection molding machine for packaging application

• Performed research both independently and in team: summarized data and statistical analyses, drafted technical reports on research results for the appointed projects sponsors and presented at meetings

• Fabricating lignin-based thermoplastic composite for industrial additives, emulsion and dispersant applications. Esterification of lignin to improve its thermal processability, molecular properties and mechanical strength.

• Applying double emulsion (Water-in-Oil-in-Water) method for the compatibilization (redispersion of CNC after organic phase removal) of hydrophilic nanocellulose with hydrophobic ABS

• Good hand skills on chemical modifications of natural polymers and characterization techniques; FT-IR, 13C/1H- NMR, GC-MS, TGA, DSC, GPC, rheometer, spin coating & fiber electrospinning, WVTR, OTR. 2

Graduate Research Assistant Aug 2014-Dec 2016

University of Toledo, Department of Chemical Engineering

• Synthesis, characterization and morphology analysis of bio-based hybrid composite (CNC/lignin-PET) using XRD, SEM and AFM at Polymer Institute in University of Toledo

• Surface functionalization of PLA films by transamidation of the PLA ester groups with primary amines containing chemicals for the manufacturing of tissue engineering scaffolds. SUMMER INTERNSHIP
