Alireza Nazarahari
Postdoctoral researcher
Alireza started his postdoc fellowship as of Mar. 2024. He has been devoting most of his time to thermophysical characterization of Ni-based superalloys (for aerospace applications; A-tu-C project) and small scale mechanical testing of Ti-6Al-4V alloys (for aerospace applications; SMART project). His specialties are small scale mechanical testing of various alloys, advanced microscopy, high-throughput computational screening for alloy design, and application of AI and Machine learning in alloy development.
Bilal Ousiabou
PhD student
Bilal started his PhD study in  Feb. 2022 and will focus on  developing high-throughput screening methods for accelerated alloy design and development (focusing on high entropy alloys; HEAs). His research will also include alloy production and characterization with possible high-throughput experimental work. The primary focus will be generic on alloys and later during the 2nd phase of his PhD research he will validate developed methodologies on specific group of alloys (most likely Fe-based alloys for Hydrogen-related applications).

Toni Bogdanoff
PhD student
Toni started his PhD study in 2018 and has been mostly focused on static and dynamic mechanical properties of Al-Si cast alloys. The effect of melt quality, microstructure and the casting process on mechanical properties (tensile and fatigue at various temperatures) as well as in-situ mechanical testing are of interest.

Keivan Amiri Kasvayee
PhD
Keivan studied high performance nodular cast iron and its mechanical behavior at micro-scale. We tried to understand the crack initiation and propagation mechanisms in multi-phase structures such as cast iron, in various working conditions. FIB-assisted digital image correlation and high resolution strain measurements around graphite particles was developed for this purpose.

* Main supervisor: Prof. Anders Jarfors
Martin Riestra
PHD (graduated as licentiate)*
Martin focused on optimization of high pressure die casting of Al-Si alloys. Through the HINT project, we tried to integrate all the process parameters required for obtaining high integrity Al-Si casting components, including (i) melt treatment, (ii) optimization of high pressure die casting, (iii) alloy design and prototyping.

Akash A. Gondhalekar
Master student
Akash is doing research on design and development of Al-based compositionally complex alloys, based on the high entropy concept, using conventional casting methods. The aim is to understand the casting process limits for production of supersturated solid-solutions without introducing too many intermetallics. 
Robert Fabian
Master student (Exchange)
Robert was conducting his master thesis with us at JU, focusing on fatigue performance of Magsimal-59 cast alloy and the effect of microstructural features on fatigue behavior. Both conventional fatigue (pull-push) and in-situ cyclic testing was conducted during his thesis.
He is now working as a functional safety engineer at Porsche Engineering.

Abhijith Muraleedharan
Master student 
Abhijith was conducting his thesis on gathering data related to empirical models calculation that are used for high entropy alloys design. He was specifically focusing on models to calculate enthalpy of formation for metallic alloys. His work has highlighted discrepancies in calculation of enthalpy in the literature.

Patrick Conway
Assist. Prof
Patrick joined us on Nov. 2018. His research focus wasphysical/mechanical metallurgy of HESAs (Ni-based at the moment - ALigHT II project). We try to modify conventional superalloys based on the HEA concept. Understanding the relationship between the microstructure and thermo-mechanical properties of the modified alloys at various temperatures is of our great interest. The end goal wasto establish a universal methodology for development of various types of metallic alloys for specific applications. Patrick also had an eye on development of lightweight medium-to-high entropy alloys.
Salil Sainis
PhD student
Salil has started his PhD study in 2018 and will focus on localized coating of Al-Si cast alloys. His research is under development but generally focused on localized deposition of protective coatings on Fe-rich intermetallics in Al-Si cast alloys

Lucia Lattanzi
Exchange Ph.D. student (Aug2018-Feb2019)
Lucia is a PhD student at Ferrara University, Italy. She joined us for around 9 months focusing on the effect of Cu solid solution on the cyclic behavior of Al-Si alloys. She conducted in-situ CT test in order to understand the effect of reinforced matrix as well as secondary phases on dynamic crack initiation and propagation in Al-Si alloys.
Ricardo Castiglieri
Master student (Exchange)
Ricardo was conducting his master thesis with us at JU, focusing T6 heat treatment on Cu-added AlSi7Mg alloys. Using In-situ cyclic testing, Ricardo was studying the influence of heat treatment on crack propagation during of cast Al alloys.

Thomas Chiavazza
Exchange Master student (May2018-Aug2018)
Thomas was a master student from ENSICAEN, France focusing on the size effect in Mg alloys. He produced Mg alloys with various ratios of thickness over grain size and studied the mechanical responses. We conduct in-situ tensile testing in order to justify the material behavior.
