STATEMENT OF QUALIFICATIONS

Dr. Rosenbloom, Principal Metallurgical Engineer at Corrosion Testing Laboratories, Inc., has experience in the field of failure analysis, materials testing, and electrochemical corrosion testing, which stems from both her academic training and her work in a variety of consulting environments.

Dr. Rosenbloom received a Bachelor of Science in Engineering degree in Bioengineering from the University of Pennsylvania.  She was awarded the Senior Design Award for her research on the Total Artificial Heart and was on the Dean’s List.  Dr. Rosenbloom also received a Doctor of Philosophy in Materials Science and Engineering from the University of Pennsylvania.  Her research there focused on fatigue crack nucleation in copper single crystals.  She developed a computer model to simulate crack initiation under conditions of random slip and modified the Scanning Tunneling Microscope to image large-scale surface topographies of experimental samples.

At Corrosion Testing Laboratories, Inc., Dr. Rosenbloom manages the failure analysis department and conducts failure investigations and assessments in order to determine the cause of failure in a variety of industrial settings.  Her investigations include failures due to mechanical failure (e.g. fatigue) as well as corrosion.  She has developed expertise in a number of metallic materials including steel, copper and copper-based alloys, and nickel-based alloys in a variety of industrial applications.  Some specific industrial applications include petrochemical processing, HVAC, chemical processing, and pharmaceutical manufacturing.  Where indicated, she also makes recommendations for remedial actions. 

In addition to her responsibilities with regards to failure assessments, Dr. Rosenbloom is responsible for conducting electrochemical testing of medical implant devices for assessment of corrosion resistance.  She consults with clients to help them interpret the results of their testing, and to help develop processing strategies that will improve the corrosion resistance of their devices.  Through experience in testing many different types of devices made from a variety of alloys, she has gained expertise in the electrochemical behavior of nitinol, stainless steel, and cobalt-chromium alloys, among others.  She recently presented a paper entitled, “An Assessment of ASTM F 2129 Test Results Comparing Nitinol to Other Implant Alloys,” at the 2006 International Conference on Shape Memory and Superelastic Technologies (SMST) and will be presenting a paper at NACE Corrosion 2007 entitled, “An Assessment of ASTM F 2129 Electrochemical Testing of Small Medical Implants - Lessons Learned”.

Previously, Dr. Rosenbloom performed a variety of failure investigations as a consultant, working with Dr. Campbell Laird of the University of Pennsylvania.  Her projects included materials and design analysis, maintenance and work-site condition analysis for determining liability, slip and fall cases, accident reconstruction and simulation, and examination of medical sutures for defects.  Dr. Rosenbloom also worked as a consultant to DuPont Marshall Laboratory in Philadelphia.  There, she provided assistance in the determination of flaw origin in coated specimens.

Dr. Rosenbloom is proficient in a variety of investigative techniques including SEM, EDAX, optical microscopy, metallography, hardness testing, microhardness testing, ultrasonic thickness measurement, dye penetrant testing, and tensile testing.

She is active in ASM International as a member of the Philadelphia Liberty Bell chapter.  She is also a member of NACE International and ASTM International, serving on the ASTM F04 Committee on Medical and Surgical Materials and Devices.  She is an adjunct member of the Delaware Association of Professional Engineers (DAPE).
