<p>Doç. Dr. Çisem ALTUNAYAR ÜNSALAN, lisans eğitimini Ege Üniversitesi Fen Fakültesi Fizik Bölümünden üçüncülük derecesi, yüksek lisans ve doktora eğitimini Ege Üniversitesi Fen Bilimleri Enstitüsü Fizik Anabilim Dalında üstün başarı ile tamamlamıştır. Akademik kariyeri boyunca biyofizik, astrofizik ve gezegen bilimleri alanlarında disiplinlerarası araştırmalar yürütmüştür. Japonya, Almanya ve Polonya’daki uluslararası araştırma deneyimlerinin ardından, <strong>Fulbright Doktora Sonrası Araştırma Bursu kapsamında NASA Johnson Space Center (Houston, Texas, ABD)’da</strong> doktora sonrası çalışmalar gerçekleştirmiştir. NASA’daki araştırmalarında özellikle karbonlu meteoritler ve gezegen yüzeylerinde bulunan karmaşık minerallerin karakterizasyonu ile su ve yaşamın yapı taşlarına ilişkin araştırmalara odaklanmıştır. </p><p>Araştırmalarım; <strong>meteoritler, astromateryaller ve gezegen bilimleri</strong> başta olmak üzere yapısal ve termofiziksel karakterizasyon çalışmalarına odaklanmaktadır. NASA Johnson Space Center’da edindiğim araştırma deneyiminin devamı niteliğinde; karbonlu, HED ve demirli meteoritlerin mineralojik ve fizikokimyasal özellikleri ile termal ve şok geçmişlerini araştırmaktayım. Güncel olarak yürütücüsü olduğum <strong>TÜBİTAK 3501 projesi (Kariyer Geliştirme Programı)</strong> kapsamında Kayakent (IIIAB) demirli meteoritindeki Widmanstätten desenleri ve Neumann çizgilerinin oluşum mekanizmalarını inceleyerek, elde edilen bulguların <strong>NASA Psyche görevi</strong> ve metalik asteroitlerin evriminin anlaşılmasına katkı sağlaması üzerine çalışmalarımı sürdürmekteyim.</p>
