Just Fracture Matches

In episode two of the 2018 IPTES season, Just Science interviews Dr. Ashraf Bastawros from Iowa State University. Dr. Bastawros discusses how fracture mechanics principles can be used with statistical learning tools to give quantitative results. Explore the mind of an engineer and hear how leveraging other disciplines can aid forensic science.

Dr. Ashraf Bastawros’ research focuses on the micro-scale properties and behavior of engineered materials, including single-crystal and polycrystalline materials, thin films and multi-layers, porous solids, and biological materials. His strength is in linking microstructures and continuum theory through fundamental and applied experimental research. He has developed novel experimental techniques to (1) reveal the nature of deformation heterogeneity at the material microstructure length scale and (2) measure the thickness and properties of ultrathin films in the nanometer range. He has redeveloped almost the entire curriculum of mechanics of materials at Iowa State University (ISU). He has nurtured and mentored undergraduate and graduate students and junior faculty in the area of the micromechanics of materials: two assistant professors, one laboratory technicians, three post-doctoral scholars, eight PhD candidates (including two underrepresented racial and/or ethnic minority students [URMs]), 22 MS students, and 50 research experience for undergraduate participants (five URMs). Five undergraduate research assistants have attended graduate school, and one former PhD student has started a tenure-track faculty position at Georgia Tech. As the lead principal investigator (PI) or Co-PI, Dr. Bastawros has managed research grants in excess of $10 million. He has authored and coauthored more than 80 technical publications in journals and conference proceedings with 100 citations annually, on average, and nearly 1,600 total citations. He is also the recipient of a National Science Foundation (NSF) Faculty Early Career Development Program (CAREER) award, an ISU Young Engineering Faculty Research Award, and many other honors and best paper awards.

Just Nature’s Patterns

Season three, episode one of Just Science kicks off with our host, Dr. John Morgan, interviewing John Vanderkolk from the Indiana State Crime Laboratory. Vanderkolk discusses his belief in the importance of challenging your teachers and how nature’s patterns are apparent throughout friction ridge evidence.

Mr. John R. Vanderkolk received a Bachelor of Arts degree in forensic studies and psychology from Indiana University in 1979. He became an Indiana State Police trooper in 1979 and then a crime scene technician in 1983. In 1984, he was assigned as a criminalist in the laboratory, where he was trained in the disciplines of latent print, shoe/tireprint, firearm/toolmark, and fracture/physical comparative examinations. He was promoted to laboratory manager in 1996. He retired as a police officer in 2005, was rehired as a civilian, and is currently the manager of the Indiana State Police Laboratory in Fort Wayne. Mr. Vanderkolk has delivered many lectures and workshops related to forensic comparative science at many international or regional seminars, criminal justice agencies, and universities. Some of his other professional activities include having been a member of the Scientific Working Group on Friction Ridge Analysis, Study and Technology and the National Institute of Standards and Technology (NIST)/National Institute of Justice (NIJ) Expert Working Group on Human Factors in Latent Print Analysis. He is currently a member of the editorial board for the Journal of Forensic Identification and the Physics/ Pattern Scientific Area Committee for the NIST Organization of Scientific Area Committees. Mr. Vanderkolk was awarded ‘Distinguished Member’ in the International Association for Identification (IAI), was a member of the IAI’s Standardization II Committee, was the chair of the IAI’s Forensic Identification Standards Committee, and is the chair of the IAI’s Forensic Comparative Examination Committee. Mr. Vanderkolk has authored or co-authored numerous journal articles on topics related to forensic comparative science. Additionally, he authored the ‘Examination Process’ chapter of The Fingerprint Sourcebook and the book, Forensic Comparative Science – Qualitative Quantitative Source Determination of Unique Impressions, Images, and Objects. He has been collaborating with Dr. Thomas Busey of the Indiana University Department of Psychological and Brain Sciences since 2002, studying expertise in latent print examiners. He has been collaborating with Drs. Ashraf Bastawros and Barbara Lograsso of Iowa State University on fractured metal examinations. Furthermore, he was a consultant for the US Department of Justice, Office of the Inspector General, and addressed the erroneous determination that Brandon Mayfield was the source of a fingerprint in the Madrid bombing case.
