Silvia ha conseguito un Master in Biologia Marina presso la Texas A&M University e una Laurea in Scienze Ambientali all'Università di Venezia. Svolge ricerche sui cetacei del Mediterraneo dal 2000, e dal 2006 ha lavorato come principal field investigator per progetti di ricerca svolti da Dolphin Biology and Conservation, OceanCare e Istituto Tethys in Grecia (Golfo di Corinto, Golfo di Evia settentrionale e meridionale, Golfo di Arta, Golfo di Argo, Arcipelago Interno del Mar Ionio orientale) e in Italia (Veneto, Puglia e Sardegna). Ha preso parte a campagne oceanografiche in Adriatico (in collaborazione con CNR-ISMAR); partecipato a survey sui cetacei nella Baia di Santa Monica, California (in collaborazione con Ocean Conservation Society); svolto uno studio pilota di foto-identificazione dalla costa per studiare i tursiopi nel Galveston Ship Channel, Texas (in collaborazione con il Marine Mammal Behavioral Ecology Group, Texas A&M University). Ha intervistato centinaia di pescatori in Italia e in Grecia. I suoi strumenti di ricerca preferiti comprendono la foto-identificazione e l'utilizzo di modelli statistici per studiare l'abbondanza, la distribuzione, l'organizzazione sociale, l'utilizzo dell'habitat e le interazioni con la pesca dei cetacei. Al momento il suo principale soggetto di ricerca sono i delfini al largo delle coste del Veneto. Silvia ha al suo attivo circa 60 contributi scientifici. E' Direttrice esecutiva di Dolphin Biology and Conservation e Ricercatrice associata di OceanCare.
