Subject: Intro from Japan

Greetings from Japan!

My name is Nobuhiro Minaka. I am a senior researcher of the National
Institute of Agro-Environmental Sciences (Laboratory of Statistics),
Tsukuba. I am interested in mathematical problems in systematic biology,
especially in phylogenetics and morphometrics. My doctoral dissertation
(University of Tokyo, 1985) is an order-theoretical formalization of
cladistic theory.

My main interest is algebraic properties of the _MPR-space_ (the set of
Most Parsimonious Reconstructions) estimated on a given cladogram.
Reconstructing hypothetical character states is an important problem in
phylogenetic analysis and in character analysis. Enumerating all MPRs
(including ACCTRAN and DELTRAN) does not lead automatically to a
satisfactory description of those MPRs. I am now writing papers on MPR and

I am also working on the Japanese translation of Dr Elliott Sober's
_Reconstructing the Past_ (MIT Pr., 1988).
