Anthony Crawfordhttps://bios.inl.gov/Lists/Researcher/DisplayOverrideForm.aspx?ID=730Anthony CrawfordDr. Anthony Crawford is an R&D scientist/engineer in the INL’s fusion, hydrogen, and measurement system’s department. He holds a B.S., M.S., and Ph.D. in mechanical engineering, an M.S. in Electrical Engineering, and an Idaho Professional Engineering License. He has been with the INL since 2007 where his technical competence has allowed him to participate in activities such as force-feedback dexterous end effector research, employing novel modified linear delta platforms, human-machine interfaces, non-destructive characterization data acquisition/processing, high rate data acquisition programming, mechatronic system development, circuit design/fabrication, mechanical design, and extensive structural/thermal/computational fluid dynamic analysis. Many of the technical analyses that he has performed include smaller scale fuel and experimental systems in the ATR and TREAT reactors as well as large scale systems (Advanced Test Reactor (ATR) Primary Coolant System, ATR core, and TREAT reactor). These experiences have equipped him with an understanding of the environmental conditions and expected system behavior (e.g. irradiation based swelling, oxidation, flow rates, temperatures, and stress/strains) applicable to reactor based research. <div class="ExternalClassF00214EE5A824396B79C40144E4269A7"><p>​Ph.D., Engineering and Applied Sciences - Idaho State University<br>M.S., Electrical Engineering - University of Idaho<br>M.S., Mechanical Engineering - University of Idaho<br>B.S., Mechanical Engineering - Idaho State University</p></div><div class="ExternalClassB313C615B8F24986A0153EBF19D60F65"><p>​Mechatronic and Intelligent Systems<br>Haptic (Force-Feedback) Devices and User Interfaces<br>Sensors and Non-Destructive Evaluation<br>Dynamic Systems<br>Programing</p></div><div class="ExternalClass2C170DEA703649F496ECCCB3C8EA31B4"><p>U.S. Technical Advisory Group (TAG) to ISO TC 299 Robotics</p></div><div class="ExternalClass91DE5B40845F4B64B618546D0FB6D216"><p>Crawford, A.
