ABOUT ME

I got my PhD degree from department of Geology; University of Vienna.
I received my M.Phil and MSc in Environmental Science degrees from Pakistan.
Currently I am working as Visiting Faculty at Quaid-I-Azam University, Islamabad, Pakistan.

My research interests are Anthropocene, Geochemistry, Climate Change and ecotoxicology.

My future research focus will be on anthropogenic contamination in the environmental archives of Pakistan by assessing different markers for the Anthropocene using multidisciplinary approach.

PROJECT DESCRIPTION


The recognition of anthropogenically induced, fundamental Changes in the Earth System led to the proposition of the Anthropocene as a potential new chronostratigraphic unit of the Geological Timescale.


Trace element concentrations in sedimentary archives, historical mining, and archaeological sites have been widely used as signals for anthropogenic contamination.


The archaeological sites of Hund and Gor Khuttree within the Peshawar Basin, NW Pakistan preserve stratified gravels that provide information about the historical anthropogenic controls on the distributions of trace elements. The youngest floodplain sediments and important archeological sites are incorporated to understand the anthropogenic controls on the distribution of various elements in the area.


Various geochemical signals revealed the palaeoclimatic variation and possible anthropogenic influence especially during the latest Holocene in the Peshawar basin (Gandahara area). Geochemical signals from the mid-20th century reflect anthropogenic contributions to the local system and correlate to the suggested base of a formalized Anthropocene. Archaeological evidences from the Peshawar Basin, NW Pakistan demonstrate clear anthropogenic activity since the demise of the late Pleistocene glaciation.
