Delovne izkušnje
- Znanstveni sodelavec na Institutu Jožef Stefan, Odsek za reaktorsko tehniko, od januarja 2019.
- Svetovalec v raziskavah na Nuclear Research and Consultancy Group (NRG), Petten, Nizozemska, februar 2017 - december 2018. CFD specialist v raziskovalni skupini in podpora pri zasnovi novih naprav za produkcijo medicinskih izotopov (npr. molibden-99) v HFR (ang. High Flux Reactor) reaktorju. Moje glavne raziskovalne teme so obsegale računske simulacije tekočin in prenosa toplote v različnih jedrskih gorivih - od kompleksnih RANS simulacij v tlačnovodnem gorivnem svežnju do natančnih LES in DNS simulacij v oplodnem reaktoru hlajenim s tekočim svincem.
- Mladi raziskovalec na Institutu Jožef Stefan, Odsek za reaktorsko tehniko, avgust 2011 - januar 2017. V skupini za jedrsko termohidravliko sem se v sklopu svoje doktorske disertacije ukvarjal z modeliranjem turbulentnega toka v gorivnem svežnju tlačnovodnega reaktorja.
- Sodelovanje z raziskovalno skupino Pipistrela, 2010-2011. V sklopu svojega diplomskega dela sem zasnoval in kalibriral Pitotovo cev za merjenje hitrosti in vpadnega kota letala.
- Sodelovec Observatorija ÄŒrni Vrh in opazovalnega projekta PIKA. Leta 2004 razvil senzor oblakov. Od leta 2008 operater na 60-centimetrskem robotiziranem teleskopu, odkril pet supernov in NEO asteroid 2015 SO2.
