Cercetare:
Munca mea in cercetare a abordat :
– ciclarea si efectele metalelor, inclusiv semnificatia lor pentru factorii de decizie (evaluarea riscului, managementul zonelor contaminate).
– managementul capitalului natural la nivel local si regional (proiectare retelelor ecologice in sisteme fluviale, evaluarea resurselor si serviciilor naturale si proiectarea planurilor de restaurare)
– modele matematice integrate in biogeochimia metalelor, conceptul de management integrat al mediului, constrangeri socio-economice asupra implementarii unui management integrat al mediului
– conceptul de ierarhie de sisteme in ecologie – aspecte ontologice si epistemice, modele teoretice, relatia cu teoriile evolutioniste
