Heiss investigates macrobotanical remains, such as seeds, fruits, wood and charcoal. He is known for pioneering methods using amorphous charred objects (ACOs) as a source of information for culinary archaeology.[4][5][6][7][8][9][10] His work addresses cultures from Neolithic up to early modern period contexts in central Europe and the Mediterranean.
National and international media have reported on findings linked to Heiss's research on numerous occasions over the years.[11] In 2019, the find of three charred cereal-based rings from Late Bronze Age Austria was compared to bagels[12] and Cheerios[13] by some media. In May 2020, coverage in German-language outlets (including Der Spiegel and ORF Science) quoted Heiss on evidence for possible beer brewing around Lake Constance and Lake Zurich in the 4th millennium BCE, based on a new microstructural marker for malting.[14][15] In 2022, media outlets covered the discovery of an early Byzantine business and gastronomy district at Ephesos by an ÖAW team, for which Heiss conducted archaeobotanical analyses.[16][17][18]

In Austrian public broadcasting, Heiss has been discussing archaeobotany in a 31-episode Radio Wien series in 2012[19] and five Ö1 features in 2019 and 2020.[20][21][22][23][24]
He has also contributed substantially to exhibitions on various topics, such as on the Iceman,[25] "magical" plants,[26] or ancient beer.[27]
