Indah Emilia Wijayanti has been started her career as a lecturer at the Department of Mathematics Universitas Gadjah Mada in 1994. She was a Deutsche Akademische Austauschdienst (DAAD) scholarship holder for the doctoral program in Germany. Her dissertation entitled Coprime Comodules was successfully completed in 2006 at the Mathematisches Institut, Heinrich Heine University of Duesseldorf.
After that she plays some active roles to develop research in algebra. She was the coordinator of the Indonesian Algebra Society (Komunitas Peminat Aljabar, KPA) from 2007 – 2011. Moreover, she is also active in the professional organization, i.e. the Indonesian Mathematical Society (IndoMS). Currently, she has the mandate as President of IndoMS for the period 2020-2022. She is also the Editor in Chief of the Journal of the Indonesian Mathematical Society (JIMS) (2019 – present).
In the Department of Mathematics, she leads for developing the Algebra Research Group for two periods and more (2007 – 2010, 2011 – 2015, 2022 – 2025). In 2016 – 2021 she became Secretary of the Mathematics Department.
Her commitment to developing algebra research can be seen from several research grants she received including the DAAD for the Re-Invitation Program (2013) in Germany and the Fulbright Senior Research Program (2016) for research visits to the Ohio University Center of Ring Theory and its Applications (OCRA), Athens, USA. Moreover, she also a grantee for several Indonesian research grant scheme, e.g. Hibah Penelitian Dasar, Hibah Penelitian Pasca Doktor, Hibah Penelitian Disertasi Doktor, Hibah Penelitian Tesis Magister, Hibah Penelitian PMDSU, World Class Professor (B), Hibah Rekognisi Tugas Akhir.
She was confirmed as a professor of mathematics on September 15, 2020 with an inaugural speech entitled Research and the Role of Abstract Algebra in the Development of Science in the Present and Future.
During her doctorate, Indah Emilia Wijayanti did some observation in prime ring and module also their dualizations, namely coprime comodule and coalgebra. After she finished her study, she has developed various primeness of (sub)modules, for example weakly prime (sub)modules, endoprime (sub)modules, endocoprime (sub) modules.
She also has studied the clean ring and module, and dualized the notions into comodules and coalgebras. She looked into the structures involved in her research and found that there is a very strong relationship between the category of module and its ground ring. Using the concept of generator and the generalization, she obtain a significant result is the emergence of a definition of a relative basis which is expected to accommodate modules which has no conventional basis.
Recently, she conducts the ring fractions and types of orders, which were then generalized to become fraction modules over ring orders. The generalization of Dedekind and Krull domain are observed.
As applications, she studies post-quantum cryptography, for examples NTRU, Matrix NTRU, GTRU and some kind of lattice based cryptography which involves algebraic structures.
Starting from derivation on ring and its modification, she is interested in derivation on module as the generalization. Moreover, she is looking after the application in quantum physics and C*-algebra.
