APT 2019 User Conference Session Leaders

The 2019 Atom Probe Tomography User's Conference will feature a wide range of dynamic, functional session topics. This year's topics will include:

Workshop Topic #1 – Wednesday, 9:00AM – 12:00PM

Rob Ulfig 

 Topic: CAMECA Updates 
 Session Leader: Rob Ulfig
 Robert Ulfig
joined Imago (Now CAMECA Instruments Inc.) in 2001 and has worked in hardware and software development and as the Applications Lab Manager for the Local Electrode Atom Probe Microscope (LEAP®).  He now works as CAMECA’s EIKOS™ Product Manager integrating the activities and requests from internal and external customers into the latest and greatest of CAMECA’s software and hardware. 
Robert previously worked at Advanced Micro Devices’ sub-micron development center in Sunnyvale CA, and graduated from The University of Wisconsin-Madison with Materials Science and Engineering and Nuclear Engineering and Engineering Physics degrees. 

Workshop Topic #2 – Wednesday, 1:30PM – 5:00PM
Topic: Atom Probe Tomography of Environmentally Sensitive Materials
Session Leaders: Stephan Gerstl and Daniel Perea

Stephan Gerstl 

 Stephan Gerstl
is a senior scientist at ETH Zurich’s microscopy center, ScopeM and lecturer in the Department of Materials Science.  Besides teaching courses & workshops at both ETH and EPFL and instructing users of the atom probe   facility, he developed the first cryo-transfer-enabled LEAP, enabling the localization of individual H atoms within steels and stimulating APT analysis capabilities of soft materials.

 During his studies, Gerstl held positions in Los Alamos National Laboratory and Max-Planck Institutes in Stuttgart and Dusseldorf.  After his PhD at Northwestern University in materials science, he joined the R&D division at Imago Scientific Instruments (now CAMECA Inc.), developing and then training the LEAP platform to early adaptors.  His interests are in further developing the combinatorial analytical capabilities of APT, particularly enabling the analyses of soft materials and the correlation between various tomographic techniques.

Daniel Perea

 Daniel E. Perea is a senior staff scientist at the Environmental Molecular Sciences (EMSL) user facility located that the Pacific Northwest National laboratory (PNNL) in Richland, Washington.

 He received his Ph.D. degree in Materials Science & Engineering from Northwestern University and completed postdoctoral studies at Los Alamos National Laboratory in New Mexico before joining PNNL.

 Daniel is an expert in Atom Probe Tomography with over 15 years of experience. Daniel’s current research interest include the development of cryo-based APT analysis of hydrated and otherwise environmentally-sensitive materials, revealing buried chemical gradients in cryogenically-prepared biological and environmental materials

Workshop Topic #3 – Thursday, 8:30 AM – 12:00 PM

Karen Henry Topic: Data Reconstruction and Analysis Techniques

Session Leader: Dr. Karen Henry

Dr. Karen Henry currently leads the atom probe tomography efforts for the Naval Nuclear Propulsion Program at Knolls Atomic Power Laboratory (KAPL).
Karen received her B.S. (2005) and M.S. (2006) in Aerospace Engineering and Ph.D. (2010) in Metallurgical Engineering from the University of Alabama.
She then completed a post-doctoral fellowship at the National Institute of Standards and Technology before joining Intel in 2012.

Her current research efforts at KAPL are focused on nanoscale microstructural characterization of materials using a combination of electron microscopy and atom probe tomography.

Workshop Topic #4 – Thursday, 1:30PM – 5:00PM

Dieter Isheim

 Topic: Innovative Specimen Preparation and Applications
 Session Leader: Dieter Isheim

 Dr. Dieter Isheim is a research associate professor of materials science and engineering at Northwestern University and manages the
Northwestern University
 Center for Atom-Probe Tomography (NUCAPT).
 After receiving a doctorate in physics and physical metallurgy from the University of Göttingen, Germany, in 1995, he joined Northwestern University for postdoctoral studies in 1996 and was reappointed at Northwestern as research faculty in 2002.

 His research interests include phase transformations in solids and multi-phase nano-structured materials and their structure-properties relationships.

 He has published more than 100 research papers in these areas. He specializes in high-resolution atomic-scale materials characterization with a focus on atom-probe tomography.

Workshop Topic #5 – Friday, 8:30AM – 12PM
Topic: APT Parameter Spaces and Best Practices
Session Leaders: Austin Akey and Stephan Gerstl

Austin Akey 
 Austin Akey received his BA in Physics from Princeton University in 2006, and his PhD in Materials Science from Columbia University in 2011.
 His post-doctoral work was done in the groups of Professor Michael J. Aziz at Harvard University’s John A. Paulson School of Engineering and Applied Sciences, and of Professor Tonio Buonassisi at MIT.

 He is active in the fields of photovoltaics, hyperdoped silicon, and solidification of metastable materials, all of which benefit greatly from APT.
 Other interests include Focused Ion Beam technique development and instrumentation design.

 He is currently a Senior Scientist at the Harvard University Center for Nanoscale Systems.
